1Then the LORD said to Moses and Aaron,
2“When someone has a swelling or rash or bright spot on his skin that could become an infectious skin disease, he must be brought to Aaron the priest or to one of his sons who is a priest.
3The priest is to examine the infection on his skin, and if the hair in the infection has turned white and the sore appears to be deeper than the skin, it is a skin disease. After the priest examines him, he must pronounce him unclean.
4If, however, the spot on his skin is white and does not appear to be deeper than the skin, and the hair in it has not turned white, the priest shall isolate the infected person for seven days.
5On the seventh day the priest is to reexamine him, and if he sees that the infection is unchanged and has not spread on the skin, the priest must isolate him for another seven days.
6The priest will examine him again on the seventh day, and if the sore has faded and has not spread on the skin, the priest shall pronounce him clean; it is a rash. The person must wash his clothes and be clean.
7But if the rash spreads further on his skin after he has shown himself to the priest for his cleansing, he must present himself again to the priest.
8The priest will reexamine him, and if the rash has spread on the skin, the priest must pronounce him unclean; he has a skin disease.

1Yahweh spoke to Moses and to Aaron, saying,
2“When a man shall have a swelling in his body’s skin, or a scab, or a bright spot, and it becomes in the skin of his body the plague of leprosy, then he shall be brought to Aaron the priest or to one of his sons, the priests.
3The priest shall examine the plague in the skin of the body. If the hair in the plague has turned white, and the appearance of the plague is deeper than the body’s skin, it is the plague of leprosy; so the priest shall examine him and pronounce him unclean.
4If the bright spot is white in the skin of his body, and its appearance isn’t deeper than the skin, and its hair hasn’t turned white, then the priest shall isolate the infected person for seven days.
5The priest shall examine him on the seventh day. Behold, if in his eyes the plague is arrested and the plague hasn’t spread in the skin, then the priest shall isolate him for seven more days.
6The priest shall examine him again on the seventh day. Behold, if the plague has faded and the plague hasn’t spread in the skin, then the priest shall pronounce him clean. It is a scab. He shall wash his clothes, and be clean.
7But if the scab spreads on the skin after he has shown himself to the priest for his cleansing, he shall show himself to the priest again.
8The priest shall examine him; and behold, if the scab has spread on the skin, then the priest shall pronounce him unclean. It is leprosy.
KJV King James Version 1769
1And the Lord spake unto Moses and Aaron, saying,
2When a man shall have in the skin of his flesh a rising, a scab, or bright spot, and it be in the skin of his flesh like the plague of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests:
3And the priest shall look on the plague in the skin of the flesh: and when the hair in the plague is turned white, and the plague in sight be deeper than the skin of his flesh, it is a plague of leprosy: and the priest shall look on him, and pronounce him unclean.
4If the bright spot be white in the skin of his flesh, and in sight be not deeper than the skin, and the hair thereof be not turned white; then the priest shall shut up him that hath the plague seven days:
5And the priest shall look on him the seventh day: and, behold, if the plague in his sight be at a stay, and the plague spread not in the skin; then the priest shall shut him up seven days more:
6And the priest shall look on him again the seventh day: and, behold, if the plague be somewhat dark, and the plague spread not in the skin, the priest shall pronounce him clean: it is but a scab: and he shall wash his clothes, and be clean.
7But if the scab spread much abroad in the skin, after that he hath been seen of the priest for his cleansing, he shall be seen of the priest again:
8And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy.
ASV American Standard Version 1901
1And Jehovah spake unto Moses and unto Aaron, saying,
2When a man shall have in the skin of his flesh a rising, or a scab, or a bright spot, and it become in the skin of his flesh the plague of leprosy, then he shall be brought unto Aaron the priest, or unto one of his sons the priests:
3and the priest shall look on the plague in the skin of the flesh: and if the hair in the plague be turned white, and the appearance of the plague be deeper than the skin of his flesh, it is the plague of leprosy; and the priest shall look on him, and pronounce him unclean.
4And if the bright spot be white in the skin of his flesh, and the appearance thereof be not deeper than the skin, and the hair thereof be not turned white, then the priest shall shut up him that hath the plague seven days:
5and the priest shall look on him the seventh day: and, behold, if in his eyes the plague be at a stay, and the plague be not spread in the skin, then the priest shall shut him up seven days more:
6and the priest shall look on him again the seventh day; and, behold, if the plague be dim, and the plague be not spread in the skin, then the priest shall pronounce him clean: it is a scab: and he shall wash his clothes, and be clean.
7But if the scab spread abroad in the skin, after that he hath showed himself to the priest for his cleansing, he shall show himself to the priest again:
8and the priest shall look; and, behold, if the scab be spread in the skin, then the priest shall pronounce him unclean: it is leprosy.
YLT Young's Literal Translation 1898
1And Jehovah speaketh unto Moses, and unto Aaron, saying,
2`When a man hath in the skin of his flesh a rising, or scab, or bright spot, and it hath become in the skin of his flesh a leprous plague, then he hath been brought in unto Aaron the priest, or unto one of his sons the priests;
3and the priest hath seen the plague in the skin of the flesh, and the hair in the plague hath turned white, and the appearance of the plague is deeper than the skin of his flesh--it is a plague of leprosy, and the priest hath seen him, and hath pronounced him unclean.
4`And if the bright spot is white in the skin of his flesh, and its appearance is not deeper than the skin, and its hair hath not turned white, then hath the priest shut up him who hath the plague seven days.
5`And the priest hath seen him on the seventh day, and lo, the plague hath stood in his eyes, the plague hath not spread in the skin, and the priest hath shut him up a second seven days.
6`And the priest hath seen him on the second seventh day, and lo, the plague is become weak, and the plague hath not spread in the skin--and the priest hath pronounced him clean, it is a scab, and he hath washed his garments, and hath been clean.
7`And if the scab spread greatly in the skin, after his being seen by the priest for his cleansing, then he hath been seen a second time by the priest;
8and the priest hath seen, and lo, the scab hath spread in the skin, and the priest hath pronounced him unclean; it is leprosy.
Darby Darby Bible 1890
1And Jehovah spoke to Moses and to Aaron, saying,
2When a man shall have in the skin of his flesh a rising or a scab, or bright spot, and it become in the skin of his flesh a sore [as] of leprosy, then he shall be brought unto Aaron the priest, or unto one of his sons the priests.
3And when the priest looketh on the sore in the skin of the flesh, and the hair in the sore is turned white, and the sore looketh deeper than the skin of his flesh, it is the sore of leprosy; and the priest shall look on him and pronounce him unclean.
4But if the bright spot be white in the skin of his flesh, and look not deeper than the skin, and the hair thereof be not turned white, the priest shall shut up [him that hath] the sore seven days.
5And the priest shall look on him the seventh day; and behold, in his sight, the sore remaineth as it was, the sore hath not spread in the skin, then the priest shall shut him up seven days a second time.
6And the priest shall look on him again the seventh day, and behold, the sore is become pale and the sore hath not spread in the skin, then the priest shall pronounce him clean; it is a scab; and he shall wash his garments and be clean.
7But if the scab have spread much in the skin, after that he hath been seen by the priest for his cleansing, he shall be seen by the priest again;
8and the priest shall look on him, and behold, the scab hath spread in the skin; then the priest shall pronounce him unclean: it is leprosy.
Douay-Rheims Douay-Rheims Bible 1899
1And the Lord spoke to Moses and Aaron, saying:
2The man in whose skin or flesh shall arise a different colour or a blister, or as it were something shining, that is the stroke of the leprosy, shall be brought to Aaron the priest, or any or of his sons.
3And if he see the leprosy in his skin, and the hair turned white and the place where the leprosy appears lower than the skin and the rest of the flesh: it is the stroke of the leprosy, and upon his judgment he shall be separated.
4But if there be a shining whiteness in the skin, and not lower than the other flesh, and the hair be of the former colour, the priest shall shut him up seven days.
5And the seventh day he shall look on him: and if the leprosy be grown no farther, and hath not spread itself in the skin, he shall shut him up again other seven days.
6And on the seventh day, he shall look on him. If the leprosy be somewhat obscure, and not spread in the skin, he shall declare him clean, because it is but a scab: and the man shall wash his clothes, and shall be clean.
7But, if the leprosy grow again, after he was seen by the priest and restored to cleanness, he shall be brought to him:
8And shall be condemned of uncleanness.

Scholars' Consensus
Commentators agree that this passage provides the priest with a diagnostic protocol for skin conditions that may be leprosy (tzaraath). The Hebrew term nega (plague, stroke) underlies the sense that such disease was seen as a divine affliction. Adam Clarke notes that the priest's pronouncement of “unclean” or “clean” is declarative: he does not make the person diseased or healed, but recognizes and names the condition. Gill observes that Aaron is specifically addressed here because the laws concern the priests: “mention is made of Aaron here, because to him and his sons belonged the judgment of leprosy.” Calvin emphasizes that not every eruption was leprosy; the priest must distinguish by marks such as hair turning white and the spot appearing deeper than the skin. The Cambridge Bible adds that the three symptoms, a rising, a scab, and a bright spot, are technical terms for incipient signs. The procedure of isolation for seven days, reexamination, and a possible second week shows cautious observation. If the condition fades and does not spread, the person is clean after washing clothes. If it spreads, the priest pronounces him unclean. The passage assumes that leprosy carried both health risks and ritual defilement, requiring the priest’s mediation to protect the community and maintain the sanctuary’s purity.
How settled is the interpretation?
Interpretive difficulty: Low
What is clear: God gave diagnostic criteria for the priest to determine whether a skin condition rendered a person ceremonially unclean, with provisions for isolation and reexamination.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of leprosy | The term <em>tzaraath</em> covers multiple skin diseases, not only Hansen's disease. | Some commentators emphasize the ritual and symbolic aspect, while others stress the actual medical condition. Both see the text as addressing physical and ceremonial dimensions. |
| Priest's authority to declare | The priest does not heal; he declares what is already true based on observable signs. | There is little disagreement here; the declarative nature is widely recognized. Some emphasize that this authority prefigures church discipline. |
| Moses and Aaron addressed together | Both were needed because the laws govern the priests, but Moses represents the legislative authority and Aaron the priestly execution. | Some note that Aaron's inclusion underscores the priests’ role as judges; others simply see it as natural since Aaron is the high priest. No major controversy. |
Historical & Cultural Context
Leprosy (tzaraath) in the Old Testament covers a range of skin diseases, including what medical texts now call Hansen’s disease, but the term was broader. Jamieson-Fausset-Brown note that the Hebrews likely contracted the disease during their stay in Egypt, where it was endemic, and the seeds of it appeared among them shortly after the Exodus. Keil and Delitzsch locate the white leprosy specifically in Asia, including Syria and Israel. The word nega (stroke) reflects a common view that such illness came as a “stroke from God” (see Deuteronomy 17:8, where “stroke” appears in a legal context). Priests, not physicians, were the inspectors because the issue was ceremonial purity as much as physical health. The camp of Israel was God’s dwelling place, and any uncleanness could pollute it. The isolation period of seven days (used twice) allowed time for the condition to declare itself. This is not a quarantine in the modern medical sense, but a ritual separation until the priest could make a definitive judgment. The language “shut up” (sagar) suggests a guarded confinement. The affected person was excluded from the community and from worship until pronounced clean. The emphasis on thorough examination, the role of Aaron alongside Moses, and the careful criteria all point to a system where God’s holiness and the people’s welfare were inseparable. The priest stood at the boundary, deciding who could approach God and who could not.
Textual Notes
The supplied sources note no significant textual variants for Leviticus 13:1-8. The Hebrew text is well preserved. Translations differ slightly in rendering symptoms (e.g., “rising” vs. “swelling,” “scab” vs. “rash”) but these reflect vocabulary choices, not manuscript differences.
Reception History
Early church fathers such as Origen interpreted leprosy allegorically as a type of sin, with the priest’s examination representing spiritual discernment. Medieval commentators focused on the priest’s judicial authority. Reformation writers like Calvin emphasized the distinction between the disease itself and the ceremonial declaration, arguing that the priests did not create uncleanness but recognized it. Modern scholarship examines the medical and ritual aspects together, often comparing these laws with ancient Near Eastern hygiene codes. The passage has been used to illustrate the need for careful examination of one’s spiritual condition and the role of church leaders in maintaining community purity.
Preaching This Verse
Three-point outline
- The Priest’s Examination: God calls Moses and Aaron to establish who may examine and declare. The priest looks closely at the skin, checking for depth and hair color. The church today must care for the whole person, including physical and spiritual health, without confusion of roles.
- The Signs of Uncleanness: White hair and deeper skin mark leprosy. The spread of a scab after apparent healing confirms it. Sin, like leprosy, often starts small and spreads. The community needs wise spiritual leaders to help discern when sin has become a serious matter.
- The Path to Cleanness: A fading, non-spreading spot leads to the pronouncement of clean, but the person must wash clothes. Even minor conditions required washing. Small sins need Christ’s cleansing. The ultimate pronouncement comes from the great High Priest.
Five-point outline
- Initial symptoms: swelling, scab, bright spot, the many ways a problem can appear.
- First examination: the priest determines depth and hair color, a preliminary judgment.
- First isolation: seven days of waiting to see if the condition develops.
- Second examination and possible second isolation: further observation for stubborn cases.
- Final declaration: clean if faded and not spread, unclean if spread, a definitive word.
Illustration hooks
- A doctor who watches a mole for changes: the priest’s role as a careful diagnostician.
- A teacher marking a test: the priest declares, but the work is the student’s.
- A gardener culling a blighted plant: protecting the whole crop requires hard decisions.
Questions your congregation is asking
- Why does God care so much about a skin disease? What does this say about his holiness?
- How can I know if I am spiritually “clean” before God?
- Does this mean we should separate people with diseases today? No, but we can learn about discernment and restoration.
Leading a Discussion
This passage shows God’s concern for both physical health and spiritual purity through the priestly system. The detailed procedure reflects his guidance for community life. As you discuss, think about how the Old Testament laws point to Christ, who cleanses us from sin.
Discussion questions
- Read Leviticus 13:1-8. What is the priest’s first action? Why does God assign this role to priests rather than to Moses alone?
- The priest examines three signs: the depth of the spot, the hair color, and whether it spreads. What does this careful process tell us about God’s character?
- Why is the person “shut up” for seven days, and then possibly another seven? What spiritual lesson might there be in waiting for a verdict?
- In verse 6, the person washes his clothes and is clean. Why are washing and patience linked here? How does this connect to baptism or to our daily walk?
- Verse 7 describes a case where the scab spreads after the person has been examined. How does this warn us about sin that seems healed but returns?
- In what ways does Jesus act as our High Priest, examining and cleansing us? Consider Hebrews 4:14-16.
- How can the church today apply the idea of “pronouncing clean or unclean” in pastoral care without becoming harsh or exclusionary?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke draws a parallel between the priest's declaration of a leper as clean or unclean and the apostles' authority to bind and loose. In both cases the power is strictly declarative: the priest or minister pronounces what is already true based on clear, infallible evidence, not by any power to actually change the person's state.
Calvin's Commentaries Reformed 1564
Calvin clarifies that the biblical term for leprosy covers a wider range of skin conditions than the incurable disease modern medicine calls elephantiasis. He notes that the priests had to observe specific marks to distinguish a curable scab or itch from true leprosy, since not every eruption made a person unclean.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge Bible highlights that the Hebrew term for "plague" literally means "a stroke," reflecting the belief that leprosy was a direct affliction from God. The commentator notes three distinct Hebrew words for skin blemishes, all describing an angry-looking boil. The leper was rejected as one "smitten of God."
Geneva Bible Notes Reformed 1599
The Geneva Notes highlight the careful process God prescribed for diagnosing leprosy. The priest examines the sore's depth and hair color, then isolates the person for up to fourteen days before making a judgment. This method protected the community while preventing hasty or unfair condemnation.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that the leprosy in this chapter is not a natural disease but a supernatural affliction from God, inflicted for sin and uncleanness. He interprets it as a type of humanity’s innate corruption, which only Christ the great High Priest can cleanse through his blood. The priestly procedures therefore point to the gospel.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB argues that leprosy among the Hebrews was not hereditary but contracted from their Egyptian oppressors, caused by hard labor, poor diet, and harsh conditions. Priests served as physicians, examining skin blemishes and ordering quarantine to prevent contagion. The required washing after release symbolized the inner purity the Mosaic law aimed to promote.
Lange's Commentary Reformed 1857
Lange treats leprosy as a companion to the uncleanness of birth, representing all the ways of death and sickness. He sees it as a "speaking picture" of sin, a death element in the blood that spreads by corruption. No human remedy is given; the le
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry emphasizes that the priest's careful examination of leprosy was not merely medical but ceremonial and spiritual. The law gave the priest authority to pronounce a person clean or unclean based on observed signs, making the condition a matter of religious separation and symbolic of sin's defiling nature.
