15And as he sat at table in his house, many tax collectors and sinners were sitting with Jesus and his disciples; for there were many who followed him. 16And the scribes of the Pharisees, when they saw that he was eating with sinners and tax collectors, said to his disciples, "Why does he eat with tax collectors and sinners?" 17And when Jesus heard it, he said to them, "Those who are well have no need of a physician, but those who are sick; I came not to call the righteous, but sinners."
Mark 2:14-17 (RSV)
