Or what woman, if she had ten drachma coins, if she lost one drachma coin, wouldn't light a lamp, sweep the house, and seek diligently until she found it? When she has found it, she calls together her friends and neighbors, saying, 'Rejoice with me, for I have found the drachma which I had lost.'

Even so, I tell you, there is joy in the presence of the angels of God over one sinner repenting.

Luke 15:8–10
