'Fast' in the Bible

And they said to him, "The disciples of John fast often and make prayers--likewise also the [disciples] of the Pharisees--but yours are eating and drinking!"

So he said to them, "You are not able to make the {bridegroom's attendants} fast as long as the bridegroom is with them, [are you]?

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

But the [seed] on the good soil--these are the ones who, [after] hearing the word, hold fast to [it] with a noble and good heart, and bear fruit with patient endurance.

I fast twice a week; I give a tenth of all that I get.'
