18 Once when John's disciples and the Pharisees were fasting, some people came to Jesus and asked, "Why don't your disciples fast like John's disciples and the Pharisees do?" 19 Jesus replied, "Do wedding guests fast while celebrating with the groom? Of course not. They can't fast while the groom is with them. 20 But someday the groom will be taken away from them, and then they will fast.
