Luke 15:6-9

6and being come to the house, calls together the friends and the neighbours, saying to them, Rejoice with me, for I have found my lost sheep.

7I say unto you, that thus there shall be joy in heaven for one repenting sinner, [more] than for ninety and nine righteous who have no need of repentance.

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.
