Thematic Bible: Lost piece of silver

Or what woman having ten drachmas, if she loses one drachma, does not light a lamp and sweep the house and seek diligently until she finds it? And when she has found it, she calls her friends and her neighbours together, saying, Rejoice with me, for I have found the drachma 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.
