'Fast' in the Bible

And the disciples of John and of the Pharisees used to fast: and they come and say unto him, Why do the disciples of John and of the Pharisees fast, but thy disciples fast not?

And Jesus said unto them, Can the children of the bridechamber fast, while the bridegroom is with them? as long as they have the bridegroom with them, they cannot fast.

But the days will come, when the bridegroom shall be taken away from them, and then shall they fast in those days.

But a heavy squall came on, and the waves were now dashing into the boat, so that it was fast filling.

(For the Pharisees and all the Jews do not eat unless they perform a ritual washing, holding fast to the tradition of the elders.

And when they come from the marketplace, they do not eat unless they wash. They hold fast to many other traditions: the washing of cups, pots, kettles, and dining couches.)

Ye leave the commandment of God, and hold fast the tradition of men.
