Luke 15:3

15:2 And the Pharisees and scribes complained, saying, "This Man receives sinners and eats with them."

15:3 So He spoke this parable to them, saying:

15:4 "What man of you, having a hundred sheep, if he loses one of them, does not leave the ninety-nine in the wilderness, and go after the one which is lost until he finds it?
