'Fast' in the Bible

And the disciples of John and the Pharisees were fasting; and they come and say to him, Why do the disciples of John and the disciples of the Pharisees fast, but thy disciples fast not?

And Jesus said to them, Can the sons of the bride-chamber fast while the bridegroom is with them? As long as they have the bridegroom with them they cannot fast.

But days will come when the bridegroom shall have been taken away from them, and then shall they fast in that day.
