Luke 15:6-9

6And when he cometh home, he calleth together his friends and his neighbors, saying unto them, Rejoice with me, for I have found my sheep which was lost. 7I say unto you, that even so there shall be joy in heaven over one sinner that repenteth, more than over ninety and nine righteous persons, who need no repentance.

8Or what woman having ten pieces of silver, if she lose one piece, doth not light a lamp, and sweep the house, and seek diligently until she find it? 9And when she hath found it, she calleth together her friends and neighbors, saying, Rejoice with me, for I have found the piece which I had lost.
