Matthew 18:26-30

So the slave fell to the ground and prostrated himself before him, saying, ‘Have patience with me and I will repay you everything.’

And the master of that slave felt compassion, and he released him and forgave him the debt.

But that slave went out and found one of his fellow slaves who owed him a hundred denarii; and he seized him and began to choke him, saying, ‘Pay back what you owe!’

So his fellow slave fell to the ground and began to plead with him, saying, ‘Have patience with me and I will repay you.’

But he was unwilling, and went and threw him in prison until he would pay back what was owed.
