Luke 15:4-6
15:4 “Which one of you, if he has a hundred sheep and loses one of them, would not leave the ninety-nine in the open pasture and go look for the one that is lost until he finds it?
15:5 Then when he has found it, he places it on his shoulders, rejoicing.
15:6 Returning home, he calls together his friends and neighbors, telling them, ‘Rejoice with me, because I have found my sheep that was lost.’
