Luke 15:1-6

1 Now all the tax collectors and sinners were coming near to listen to him.
2 And the Pharisees and the scribes were grumbling and saying, "This fellow welcomes sinners and eats with them."
3 So he told them this parable:
4 "Which one of you, having a hundred sheep and losing one of them, does not leave the ninety-nine in the wilderness and go after the one that is lost until he finds it?
5 When he has found it, he lays it on his shoulders and rejoices.
6 And when he comes home, he calls together his friends and neighbors, saying to them, "Rejoice with me, for I have found my sheep that was lost.'
