Matthew 18:30-35

18:30 But he refused. Instead, he went out and threw him in prison until he repaid the debt. 18:31 When his fellow slaves saw what had happened, they were very upset and went and told their lord everything that had taken place. 18:32 Then his lord called the first slave and said to him, ‘Evil slave! I forgave you all that debt because you begged me! 18:33 Should you not have shown mercy to your fellow slave, just as I showed it to you?’ 18:34 And in anger his lord turned him over to the prison guards to torture him until he repaid all he owed. 18:35 So also my heavenly Father will do to you, if each of you does not forgive your brother from your heart.”
