Luke 15:8-10

Or 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? And 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. Even so, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth.
