Jesus dines with tax collectors and sinners at Matthew's house, drawing criticism from the Pharisees. He defends his actions by saying that those who are sick need a doctor, not the righteous, and that he has come to call sinners to repentance. Jesus also explains that his disciples do not fast because fasting is inappropriate while the bridegroom is present, referring to himself, but that a time will come when he is taken away and fasting will be suitable. He uses metaphors of patching old garments and putting new wine in old wineskins to illustrate that his teachings require a new approach, not just reforming the old religious system.
