Matthew 18:31-35

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? And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due. So shall also my heavenly Father do unto you, if ye forgive not every one his brother from your hearts.
