Matthew 18:28-34
18:28 After he went out, that same slave found one of his fellow slaves who owed him one hundred silver coins. So he grabbed him by the throat and started to choke him, saying, ‘Pay back what you owe me!’
18:29 Then his fellow slave threw himself down and begged him, ‘Be patient with me, and I will repay you.’
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.
