Matthew 9:14-15

Then the followers of John the Baptist came to Jesus, asking, “Why is it that we and the Pharisees fast often, but your disciples don't fast at all?” Jesus answered, “Do you expect the guests at a wedding party to be sad as long as the bridegroom is with them? Of course not! But the day will come when the bridegroom will be taken away from them, and then they will fast.
