Matthew 18:32-35

32 His master called the first servant and said, ‘You wicked servant! I forgave you all that debt because you appealed to me.

33 Shouldn't you also have mercy on your fellow servant, just as I had mercy on you?'

34 His master was furious and handed him over to the guard responsible for punishing prisoners, until he had paid the whole debt.

35 " My heavenly Father will also do the same to you if you don't forgive your brother or sister from your heart."
