Matthew 18:29-30, 33-35

So his fellow slave fell on his knees and begged him earnestly, ‘Have patience with me and I will repay you.’ But he was unwilling and he went and had him thrown in prison until he paid back the debt.

Should you not have had mercy on your fellow slave [who owed you little by comparison], as I had mercy on you?’ And in wrath his master turned him over to the torturers (jailers) until he paid all that he owed. My heavenly Father will also do the same to [every one of] you, if each of you does not forgive his brother from your heart.”
