Matthew

5:14 Ye are the light of the world. A city that is set on an hill cannot be hid.

5:15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.

5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.

Mark

4:21 And he said unto them, Is a candle brought to be put under a bushel, or under a bed? and not to be set on a candlestick?

4:22 For there is nothing hid, which shall not be manifested; neither was any thing kept secret, but that it should come abroad.

Luke

8:16 No man, when he hath lighted a candle, covereth it with a vessel, or putteth it under a bed; but setteth it on a candlestick, that they which enter in may see the light.

8:17 For nothing is secret, that shall not be made manifest; neither any thing hid, that shall not be known and come abroad.
