Mark 2:14-17

14And passing by, he saw Levi the [son] of Alphaeus sitting at the tax-office, and says to him, Follow me. And he rose up and followed him.

15And it came to pass as he lay at table in his house, that many tax-gatherers and sinners lay at table with Jesus and his disciples; for they were many, and they followed him.

16And the scribes and the Pharisees, seeing him eating with sinners and tax-gatherers, said to his disciples, Why [is it] that he eats and drinks with tax-gatherers and sinners?

17And Jesus having heard [it] says to them, They that are strong have not need of a physician, but those who are ill. I have not come to call righteous [men], but sinners.
