Luke 15:8-10

8Or, what woman having ten drachmas, if she lose one drachma, does not light a lamp and sweep the house and seek carefully till she find it?

9and having found it she calls together the friends and neighbours, saying, Rejoice with me, for I have found the drachma which I had lost.

10Thus, I say unto you, there is joy before the angels of 1God for one repenting sinner.
