Thematic Bible: Lost piece of silver

"Or what woman, if she has ten silver coins and loses one of them, does not light a lamp and sweep the house, and look carefully until she finds it? And when she finds it, she calls in her friends and neighbors, and says, 'Rejoice with me, because I have found the coin which I lost!' Just so, I tell you, there is joy among the angels of God over one sinful person who repents!"
