From the Gospel according to Mark
MK 2:13-17

Jesus went out along the sea.  All the crowd came to him and he taught them. As he passed by, he saw Levi, son of Alphaeus, sitting at the customs post.  Jesus said to him, “Follow me.”  And he got up and followed Jesus.  While he was at table in his house, many tax collectors and sinners sat with Jesus and his disciples; for there were many who followed him.  Some scribes who were Pharisees saw that Jesus was eating with sinners  and tax collectors and said to his disciples,  “Why does he eat with tax collectors and sinners?”  Jesus heard this and said to them, “Those who are well do not need a physician, but the sick do.  I did not come to call the righteous but sinners.”
