Now John's disciples and the Pharisees were fasting, [i.e., going without food and/or drink for religious reasons]. Some people came and asked Jesus, "Why do John's disciples and the Pharisees' disciples fast, but your disciples do not?"

Jesus answered them, "Can the companions of the groom fast while the groom is still with them? As long as they have the groom with them they cannot fast.

But the time will come when the groom will be taken away from them. Then they will fast at that time.
