Barnes' Notes
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.
