Matthew 18:29-33

So his fellow-servant fell down and besought him, saying, Have patience with me, and I will pay thee. And he would not: but went and cast him into prison, till he should pay that which was due. So when his fellow-servants saw what was done, they were exceeding sorry, and came and told unto their lord all that was done. Then his lord called him unto him, and saith to him, Thou wicked servant, I forgave thee all that debt, because thou besoughtest me: shouldest not thou also have had mercy on thy fellow-servant, even as I had mercy on thee?
