Matthew 18:32-35

Then his master called him and said to him, You contemptible and wicked attendant! I forgave and cancelled all that [great] debt of yours because you begged me to. And should you not have had pity and mercy on your fellow attendant, as I had pity and mercy on you? And in wrath his master turned him over to the torturers (the jailers), till he should pay all that he owed. So also My heavenly Father will deal with every one of you if you do not freely forgive your brother from your heart his offenses.
