Matthew 18:28-35

But when that same servant went out, he found one of his fellow servants who owed him a hundred denarii, and seizing him, he began to choke him, saying, ‘Pay what you owe.’ So his fellow servant fell down and pleaded with him, ‘Have patience with me, and I will pay you.’ He refused and went and put him in prison until he should pay the debt. When his fellow servants saw what had taken place, they were greatly distressed, and they went and reported to their master all that had taken place. 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.”
