What is the meaning of [Hide not your light under a bushel]

Don’t be too modest to set others a good example. Here a bushel is a measure,
a container for corn, ect. The source of the proverb is Matthew, v, 15. During
the sermon on the mount Jesus said to his disciples: ‘Ye are the light of the
world. A city that is set on a hill cannot be hid. Neither do men light a
candle, and put it under a bushel, but on a candlestick; and it giveth light
to all that are in the house. Let your light so shine before men, that they
may see your good works, and glorify your _Father which is in heaven_.’
