Matthew 18:32-35

Then his master summoned him and said to him, ‘You wicked servant! I forgave you all that debt because you pleaded with me. And should not you have had mercy on your fellow servant, as I had mercy on you?’ And in anger his master delivered him to the jailers,until he should pay all his debt. So also my heavenly Father will do to every one of you, if you do not forgive your brother from your heart.”
