Thematic Bible: Lost piece of silver

"Or what woman, if she has ten silver coins and loses one coin, does not light a lamp and sweep the house and search carefully until she finds it? "When she has found it, she calls together her friends and neighbors, saying, 'Rejoice with me, for I have found the coin which I had lost!' "In the same way, I tell you, there is joy in the presence of the angels of God over one sinner who repents."
