"As Jesus was walking along, he saw a man called Matthew sitting at the tax booth; and he said to him, "Follow me." And he got up and followed him. And as he sat at dinner in the house, many tax collectors and sinners came and were sitting with him and his disciples. When the Pharisees saw this, they said to his disciples, "Why does your teacher eat with tax collectors and sinners?" But when he heard this, he said, "Those who are well have no need of a physician, but those who are sick. Go and learn what this means, 'I desire mercy, not sacrifice.' For I have come not to call the righteous but sinners.""
-Matthew 9: 9-13
