Ni se enciende una lámpara y se pone debajo de un almud, mas sobre el candelero, y alumbra á todos los que están en casa.
Nem se acende a lâmpada para se pôr debaixo de um cesto, mas sim na luminária, e ilumina a todos quantos estão na casa.
et on n’ allume pas une lampe pour la mettre sous le boisseau, mais on la met sur le chandelier, et elle éclaire tous ceux qui sont dans la maison.
Man zündet auch nicht ein Licht an und setzt es unter einen Scheffel, sondern auf einen Leuchter; so leuchtet es denn allen, die im Hause sind.
Noch steekt men een kaars aan, en zet die onder een koornmaat, maar op een kandelaar, en zij schijnt allen, die in het huis zijn;
e non si accende una lampada per metterla sotto il moggio; anzi la si mette sul candeliere ed ella fa lume a tutti quelli che sono in casa.
Ani zapalają świecy, i stawiają jej pod korzec, ale na świecznik, i świeci wszystkim, którzy są w domu.
И, зажегши свечу, не ставят ее под сосудом, но на подсвечнике, и светит всем в доме.
人點 燈， 不 放 在 斗 底下， 是放在 燈臺上，就 照亮 一 家的人。
And a burning light is not put under a vessel, but on its table; so that its rays may be shining on all who are in the house.

Scholars' Consensus
Commentators agree on the central point: light is meant to be seen, and hiding it defeats its purpose. Barnes notes that the very reason people light a lamp is for visibility, not concealment. Vincent highlights the definite article with 'the bushel' and 'the lampstand', these were standard household items, and every hearer knew their proper use. Gill reads the lamp as a figure for the Gospel itself, lit by Christ and designed to illuminate the whole house. Across traditions, the consensus is that the verse states a simple, undeniable fact: a covered lamp is a contradiction. The same holds for a disciple whose faith remains hidden. The point is not that one must force visibility, but that genuine faith, like a lit lamp on a stand, naturally sheds light. The verse sets up the exhortation in v.16: 'Let your light so shine before men.' Both description and command work together, the nature of light demands its use.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Active visibility view: The surrounding context (v.16 'let your light shine') and the purpose of light (to be seen) imply a command to make good works visible.
- Inevitable visibility view: The verse states a simple fact: a lit lamp cannot be hidden. The emphasis is on the nature of genuine faith — it will shine on its own, not on obligation.
What is clear: The verse teaches that light is meant to be seen, and that disciples must not hide their faith; the purpose of the light is to illuminate the house for the glory of God.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of the lamp | The lamp represents the light of faith, the gospel, or the believer's witness. | Gill interprets the lamp as the gospel itself, lit by Christ and set in the church. Others, including Barnes and Matthew Henry, see it as the believer's own faith and good works. Both readings agree the lamp is meant to give light. |
| Active command vs. descriptive statement | The verse describes what people naturally do with a lamp, they do not hide it. | Some commentators (Barnes, Wesley) read the verse as implying a command: believers must not hide their light. Others (Gill, more descriptive) emphasize that the light of the gospel will inevitably shine, the point is its nature, not a directive. The surrounding verse 16 tilts toward command, but the verse itself is a statement of fact. |
| The identity of 'the house' | The lamp shines on everyone present. | The Cambridge Bible notes that in Matthew, 'all who are in the house' likely refers to the Jewish people, while in Luke 'those who enter in' points to the Gentiles. Both readings affirm that the light is not exclusive, it reaches those near it. |
| The bushel as a symbol | The bushel is a common object that would conceal light. | Clarke notes that some ancient writers associated hiding a lamp under a bushel with evil intentions (murder, theft). Others simply see it as a picture of concealment, from fear, laziness, or neglect. Both interpretations caution against deliberately hiding one's faith. |
Historical & Cultural Context
In first-century Galilean homes, a clay oil lamp (λύχνος, luchnos) was a small but essential item. It burned olive oil and gave a modest flame, enough to light a single room. The lampstand (λυχνία, luchnia) was a raised pedestal, often made of pottery or metal, designed to hold the lamp aloft and spread light evenly. The μόδιος (modios) was a dry measure used for grain, common in every household, about two gallons or 8, 9 litres. To place a lit lamp under such a vessel would be both dangerous and foolish: the basket could catch fire, and the light would be blocked. Adam Clarke, drawing on ancient sources, notes that only those with evil designs, thieves or murderers, would hide a lamp under a bushel, to have secret light at night. This adds a moral dimension: hiding the light is not just impractical; it may accompany harmful actions.
The saying appears in three other gospels (Mark 4:21; Luke 8:16; 11:33), suggesting it was a memorable image Jesus used repeatedly. In Matthew's arrangement, it follows the declaration that believers are 'the light of the world' (v.14) and leads into the command of v.16. The ordinariness of the objects, lamp, basket, stand, made the lesson irresistible. Everyone knew: you do not light a lamp and then cover it. That defeats the purpose. The same holds for the light of the gospel in the lives of his followers.
Textual Notes
The consulted sources note no significant textual variants for Matthew 5:15. The manuscript tradition is stable across the major witnesses. A few later manuscripts substitute 'candle' for 'lamp' (as in the KJV), but this reflects a translation choice, not a textual difference in the Greek.
Reception History
This verse has been a cornerstone of Christian teaching on witness from the earliest centuries. The early church saw it as a call to public confession, especially during persecutions when concealment was tempting. Augustine used the image to argue that the church itself must be visible, a city on a hill. Medieval interpreters sometimes allegorized the lampstand as the church and the bushel as worldly cares or false teaching. Reformation commentators (Calvin, the Geneva Bible) emphasized the duty of every believer, not just clergy, to let their faith be seen. In modern times, the verse is frequently cited in discussions of evangelism, social engagement, and personal integrity. Its simple, memorable picture has made it one of the most quoted verses on the public nature of Christian discipleship.
Preaching This Verse
Three-point outline
- The nature of light: It is meant to be seen. A lamp’s purpose is to shine, this is not optional but built into its design.
- The temptation to hide: The bushel represents any fear, comfort, or cultural pressure that would block the light. We are often tempted to keep faith private.
- The place of witness: The lampstand is the position where light does its work. For believers, that place is wherever they live, work, and gather, the 'house' God has set them in.
Five-point outline
- The source: God is the one who lights the lamp. The light of faith is not self-generated but given.
- The obstacle: The bushel, anything that conceals the light. It may be fear of others, a desire to fit in, or simple neglect.
- The fixture: The lampstand. This is the proper place for light. In a believer's life, that means a posture of openness and availability.
- The effect: The lamp shines 'to all who are in the house.' The light is not selective; it benefits everyone near it.
- The goal: That glory goes to the Father (v.16). Visible faith is not about self-promotion but about pointing to God.
Illustration hooks
- A flashlight in a dark room: you turn it on and point it where you need to see, you don't cover the lens.
- A candle on a dinner table: set in the center so everyone can share its light. No one puts it under a bowl.
- A nightlight in a hallway: it stays on all night, small but steady, guiding anyone who passes.
Questions your congregation is asking
- 'How do I let my light shine without looking like I'm showing off?'
- 'What if my faith feels small or weak, does it still count as light?'
- 'How can I tell if I'm hiding my faith under a bushel without realizing it?'
Leading a Discussion
Jesus uses the most ordinary household object, a lamp, to teach about discipleship. The image would have been instantly clear to his hearers. Light is useless if covered.

What the Commentators Say
10 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that ancient writers associated hiding a candle under a bushel with people who had evil intentions. They would conceal a light so they could rise during the night and carry out horrid crimes like murder. This gives the verse a warning against using concealment for wicked purposes.
Barnes' Notes on the Bible Protestant 1832
Barnes explains that Jesus uses the common practice of lighting a lamp to teach a basic point: Christians are enlightened specifically so others may see and benefit. The purpose of receiving the gospel is not to conceal it but to let it shine on a dark world.
Cambridge Bible for Schools and Colleges Anglican 1880
This commentator notes that the lamp in a Jewish home sat on a tall stand, not a table. More significantly, they highlight that Matthew’s phrase “all that are in the house” refers specifically to the Jewish people, while Luke’s parallel speaks of Gentiles entering in to see the light.
Geneva Bible Notes Reformed 1599
The Geneva notes draw a simple analogy from everyday life: a lamp is lit to be placed where it can be seen, not hidden. The point is that visible good works are not an accident but the intended purpose of a believer's light, meant to shine openly for others.
Gill's Exposition of the Bible Baptist 1748
Gill interprets the candle as the Gospel and the gifts for preaching it. His distinctive point is that ministers must not hide these gifts through sloth or fear, but display them openly. He also notes the Gospel candle shines brightest near the end of the age, just as lamps flare before going out.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB highlights the familiar household imagery of a lamp placed on a stand, not covered by a basket. They note the Greek definite articles indicate common utensils everyone knew. The light shines to all in the house, stressing that Christian witness reaches everyone in ordinary daily life.
Lange's Commentary Reformed 1857
Lange presents the beatitudes as an ascending progression of spiritual life, where each blessing grows out of the one before it, from poverty in spirit to peacemaking and suffering for Christ. He stresses that Christ delivers these as gracious promises, not legal demands, deliberately contrasting the gentle tone of the gospel with the
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry emphasizes that the disciples are not simply salt for Israel, as the prophets were, but salt for the whole earth. They will influence the world not by force but by the silent, penetrating work of the gospel, which reaches hearts and preserves from corruption.
Vincent's Word Studies Evangelical 1887
Vincent points out that the Greek definite article marks the bushel and the lampstand as familiar objects found in every home. He stresses that the word often translated "candlestick" actually means a lamp-stand, since every instance in the New Testament and the tabernacle description refers to a stand for oil lamps, not a candle holder.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley presses the point that God's intent in granting spiritual light is that it be displayed openly. The very purpose of receiving this light is to let it shine, not to conceal it.
