Matthew 18:28-30

28But that same slave went out and found one of his fellow slaves who owed him a hundred denarii; and he seized him and began choking him, saying, ‘Pay what you owe!’

29So his fellow slave fell on his knees and begged him earnestly, ‘Have patience with me and I will repay you.’

30But he was unwilling and he went and had him thrown in prison until he paid back the debt.
