Or what woman having ten pieces of silver, if she loses one piece, does not light a lamp, and sweep the house, and seek diligently till she finds it? And when she has found it, she calls her friends and her neighbors together, saying, Rejoice with me; for I have found the piece which I had lost. Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repents. (Luke 15:8-10)
