Matthew 18:31-35

So when his fellow slaves saw what had happened, they were deeply grieved and came and reported to their master all that had happened.

Then summoning him, his master *said to him, ‘You wicked slave, I forgave you all that debt because you pleaded with me.

Should you not also have had mercy on your fellow slave, in the same way that I had mercy on you?’

And his master, moved with anger, handed him over to the torturers until he would repay all that was owed him.

My heavenly Father will also do the same to you, if each of you does not forgive his brother from your heart.”
