Neither do men light a candle - The word rendered "candle" means any portable light, as a lamp, candle, lantern. Compare Mark 4:21; Luke 8:16; Luke 12:35. Jesus proceeded here to show them that the very reason why they were enlightened was that others might also see the light, and be benefited by it. When people light a candle, they do not conceal the light, but place it where it may be of use. So it is with religion. It is given that we may benefit others. It is not to be concealed, but suffered to show itself, and to shed light on a surrounding wicked world.
A bushel - Greek, a measure containing nearly a peck. It denotes anything, here, that might conceal the light.

Neither do men light a candle and put it under a bushel - A bushel μοδιος: - a measure both among the Greeks and Romans, containing a little more than a peck English. From some ancient writers we learn, that only those who had bad designs hid a candle under a bushel; that, in the dead of the night, when all were asleep, they might rise up, and have light at hand to help them to effect their horrid purposes of murder, etc. See Wetstein, Kypke, Wolf, etc.

Neither do men light a candle,.... Which may be read impersonally, "a candle is not lighted": and by it may be meant the Gospel, and gifts qualifying men to preach it; which, like a candle, was lighted in the evening of the Jewish dispensation, though not confined to the land of Judea; but has shone throughout the world, being as a candle to be removed, and has been removed from place to place: wherever it is set, it gives light, more or less, and dispels darkness; it is useful both to work by and walk with; it does not always burn alike clearly, it needs looking after; it has its thieves, as candles sometimes have; and will give the greatest light towards the close of the world, as they usually do, when ready to go out. Now when a candle is lighted by men, they do not
put it under a bushel, or anything which may hide and cover it, and so hinder its light and usefulness. The Greek word rendered a "bushel", answers to the Hebrew "seah", which is the very word used in Munster's Hebrew Gospel; and this was a dry measure that held about a gallon and a half; and accordingly is rendered here by the Syriac The design of the expression is, that Christ has lighted the candle of the everlasting Gospel, and given gifts to men for the ministration of it, not to be concealed and neglected, or to be used as the servant did his lord's money, wrap it up in a napkin, and hide it in the earth. Ministers are not, through slothfulness, to neglect the gift that is in them; nor, through fear, to hide their talents, or keep back any part of the Gospel, or cover anything out of sight, which may be profitable to souls: "but" men, when they light a candle, put it
on a candlestick, and it giveth light to all that are in the house; as on the candlestick in the temple, a type of the church; where Christ has set the light of the Gospel, where it is held forth particularly by the ministers of the word, to illuminate the whole house and family of God; by the light of which poor sinners, the lost pieces of silver, are looked up; straggling souls are brought home; hypocrites and formalists are detected; and saints are enlightened, directed, and comforted. Much such a proverbial saying is used by the Jews (r):
"do not leave a vessel of balsam in a dunghill, but move it from its place, that its smell may spread, and men may receive profit from it.''

Neither do men light a candle--or, lamp.
and put it under a bushel--a dry measure.
but on a candlestick--rather, "under the bushel, but on the lampstand." The article is inserted in both cases to express the familiarity of everyone with those household utensils.
and it giveth light--shineth "unto all that are in the house."

Light a candle and put it under a bushel. A lamp, in the Revision, which is correct. Candles and candlesticks were not used in Scripture times. It would be foolishness to light a lamp and put it under a bushel measure.

Nay, the very design of God in giving you this light was, that it might shine. Mark 4:21; Luke 8:16; Luke 11:33.
