'Fast' in the Bible

Now John's disciples and the Pharisees would fast regularly. Some people came and asked Jesus, "Why do John's disciples and the Pharisees' disciples fast, but your disciples don't fast?"

Jesus replied, "The wedding guests can't fast while the groom is with them, can they? As long as they have the groom with them, they can't fast.

But the time will come when the groom will be taken away from them, and then they will fast on that day."
