Luke 15:1-6

Now all the tax collectors and sinners [including non-observant Jews] were coming near Jesus to listen to Him. Both the Pharisees and the scribes began muttering and complaining, saying, “This man accepts and welcomes sinners and eats with them.” So He told them this parable: “What man among you, if he has a hundred sheep and loses one of them, does not leave the ninety-nine in the wilderness and go after the one which is lost, [searching] until he finds it? [Matt 18:12-14] And when he has found it, he lays it on his shoulders, rejoicing. And when he gets home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, because I have found my lost sheep!’
