BSB Berean Standard Bible 2020
18When a boil appears on someone’s skin and it heals,
19and a white swelling or a reddish-white spot develops where the boil was, he must present himself to the priest.
20The priest shall examine it, and if it appears to be beneath the skin and the hair in it has turned white, the priest shall pronounce him unclean; it is a diseased infection that has broken out in the boil.
21But when the priest examines it, if there is no white hair in it, and it is not beneath the skin and has faded, the priest shall isolate him for seven days.
22If it spreads any further on the skin, the priest must pronounce him unclean; it is an infection.
23But if the spot remains unchanged and does not spread, it is only the scar from the boil, and the priest shall pronounce him clean.

20And if, when the priest seeth it, behold, it be in sight lower than the skin, and the hair thereof be turned white; the priest shall pronounce him unclean: it is a plague of leprosy broken out of the boil.
21But if the priest look on it, and, behold, there be no white hairs therein, and if it be not lower than the skin, but be somewhat dark; then the priest shall shut him up seven days:

Scholars' Consensus
Commentators agree that Leviticus 13:18-23 describes a careful diagnostic process for leprosy (tzara'at) appearing at the site of a healed boil. Gill notes that the word for ‘boil’ (shĕḥîn) covers any inflammation from a stone, stick, or hot water. Barnes explains that ‘lower than the skin’ means the spot reaches below the scarf skin, indicating deeper infection. The Cambridge Bible observes that only one seven-day isolation is required here, suggesting these cases were easier to judge than primary leprosy. Clarke adds that the priest examined whether the boil could become a source of contagion. All agree that the priest’s role was declarative: he pronounced what was already true about the person’s condition, protecting both the individual and the community from uncleanness.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Literal skin disease: The detailed physical signs (white hair, depth, spread) point to a real infectious condition, likely a form of leprosy or similar.
- Broad ritual condition: The same term applies to clothing and houses (Lev 13:47, 14:34), suggesting tzara'at is a broader category of ritual impurity, not limited to medical leprosy.
What is clear: The priest examined the site of a healed boil using observed signs to determine whether the person was clean or unclean for community membership.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of tzara'at | All traditions see tzara'at as a serious skin condition requiring isolation and priestly declaration. | Some scholars identify it with Hansen's disease; others argue it encompasses various skin ailments and even mold. The passage itself does not specify a single modern disease. |
| Priest's role | The priest acted as a diagnostician and mediator, pronouncing the person clean or unclean. | Catholic and Orthodox traditions emphasize the priest's sacramental role in declaring forgiveness, while Protestant traditions see it as a typological foreshadowing of Christ. |
| Relevance for Christians | The physical laws point to deeper spiritual truths about sin and cleansing. | Some Christians apply the passage directly to church discipline; others see it as part of the ceremonial law fulfilled in Christ and no longer binding. |
Historical & Cultural Context
Boils were a common affliction in the ancient Near East. The Hebrew word shĕḥîn is used for the boils that struck Egypt (Exodus 9:9), for Hezekiah’s illness (2 Kings 20:7), and for Job’s painful sores (Job 2:7). These passages show that boils were understood as severe, sometimes divine, judgments. The law in Leviticus treats a healed boil as a potential site for leprosy to reappear, requiring priestly examination.
The priest functioned as a public health inspector. His job was to identify signs of a contagious, disfiguring disease that would exclude a person from the camp. The criteria, white hair, depth below the skin, and spreading, were visual markers that distinguished a benign scar from a malignant infection. The seven-day quarantine allowed time for symptoms to develop or fade, preventing hasty judgments.
Israel’s camp was both a physical community and a holy sanctuary. God’s presence dwelt among them, so purity laws protected both health and holiness. This passage shows that God pays attention to the body’s wounds and healing, and that the community’s well-being requires careful oversight.
Textual Notes
The consulted sources note no significant textual variants for Leviticus 13:18-23. The Hebrew text is stable across manuscripts.
Reception History
Early church fathers like Origen and Augustine often interpreted leprosy allegorically as a symbol of sin spreading in the soul. The healed boil represented a past sin that could still hide a deeper corruption. Medieval Jewish commentators like Rashi and Maimonides (cited by Gill) focused on the practical medical criteria, discussing the types of boils and the signs of uncleanness. Reformation expositors such as Calvin and Matthew Henry emphasized the priest’s role as a type of Christ, who alone declares sinners clean. Modern scholars place the passage in its ancient Near Eastern context, comparing it to other health laws. The detailed diagnostic process continues to be read as a reminder that God cares for both body and community.
Preaching This Verse
Three-point outline
- God sees the healed wound. The priest examines the place of a healed boil, not just an active sore. God cares about what happens after healing, not only the crisis.
- Signs of deeper trouble. White hair, depth, and spread indicate the infection is not just skin-deep. Sin can appear healed but still have hidden roots.
- A priest to declare clean. The patient must go to the priest. God provides a mediator to pronounce the verdict and restore the person to community.
Five-point outline
- Examination: The priest looks carefully at the spot.
- Signs of uncleanness: White hair, depth below skin, spreading, any one of these means uncleanness.
- Isolation: If signs are uncertain, a seven-day quarantine tests the progression.
- Spread: If it spreads, it confirms leprosy.
- Stability: If it stays unchanged, it is only a scar, and the priest declares the person clean.
Illustration hooks
- A doctor checks a mole that changed after an injury, using the ABCDE rule (asymmetry, border, color, diameter, evolving). The priest used similar visual signs.
- A community quarantines during a contagious outbreak, isolating the sick to protect the vulnerable. Israel’s camp did the same.
- A scar left from a deep cut can sometimes hide an infection underneath. The priest probed below the surface.
Questions your congregation is asking
- Why does the Bible spend so many verses on skin diseases?
- What does this law teach about God’s view of the body and health?
- How does Jesus fulfill the role of the priest who examines and cleanses?
Leading a Discussion
This passage may seem distant from our lives, but it shows God’s detailed care for the physical and social health of His people. The priest’s examination prevented unnecessary isolation while protecting the community from contagious disease.
Discussion questions
- What do you notice about the priest’s role in this passage? How is it different from a medical doctor today?
- Why do you think the law includes both signs of depth and spread? What might these represent spiritually?
- What does the seven-day quarantine tell us about God’s patience and wisdom?
- How does this passage help us understand the seriousness of sin as something that can “spread” in a community?
- In what ways does Jesus act as our priest, examining and cleansing us (see Hebrews 4:14-16)?
- How can we balance the call to be holy with the call to show compassion to those who are “unclean”?
- What does this passage teach about the importance of careful, patient judgment in church discipline?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke draws on Scheuchzer's medical analysis to identify several specific types of ulcers described here, such as phlegmonic and erysipelatous infections. He observes that a person with any open sore was far more vulnerable to catching leprosy through contact than someone whose skin was whole and healthy.
Barnes' Notes on the Bible Protestant 1832
Barnes corrects two translation points. First, "lower than the skin" more accurately means the infection reaches below the outer layer of skin. Second, the phrase translated "burning boil" actually describes the scar left by an ulcer, from the literal Hebrew "burn of the ulcer."
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator notes that the Hebrew word for boil appears in the accounts of Hezekiah and Job, and in the threat of Egypt's boils. Since Egypt was known for severe skin diseases, this boil may itself be a form of leprosy. In such cases the marks were easier to recognize, requiring only one seven-day isolation period.
Geneva Bible Notes Reformed 1599
The Geneva note explains how a priest distinguishes leprosy from a harmless healing scar. A healed boil that leaves a white or reddish swelling lower than the surrounding skin, with white hairs, is leprosy and makes a person unclean. But if the spot is darker and does not spread, it is only a burn scar and the person is clean.
Gill's Exposition of the Bible Baptist 1748
Gill draws a spiritual lesson from the physical progression: a boil that appeared healed but later produces leprosy pictures apostates who return to sin. He also notes a debate among Jewish scholars about whether the spot should be called "reddish" or "exceeding glittering," citing different traditions.
Lange's Commentary Reformed 1857
Lange sees leprosy as a "death element in the stream of life," making it a vivid symbol of sin that excludes a person from God's presence. He emphasizes that the law provides no human cure, leaving the leper entirely to
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry draws attention to the careful distinctions the priest must make after a boil heals. A scar that remains low, turns white, or spreads reveals underlying corruption, but a mark that stays and darkens is harmless. This teaches that past afflictions can leave traces that need patient spiritual examination.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley specifies that the term "plague" in this passage refers specifically to leprosy, not a general epidemic or calamity. He is clarifying the meaning of the word as it applies to the disease being discussed.
