Matthew 18:32-35

Then his lord called him, and he said to him: 'You wicked servant, I forgave you all your debt, because you pleaded with me. Therefore, should you not also have had compassion on your fellow servant, just as I also had compassion on you?' And his lord, being angry, handed him over to the torturers, until he repaid the entire debt. So, too, shall my heavenly Father do to you, if each one of you will not forgive his brother from your hearts."
