Matthew 18:30-34

30 But he refused; instead, he had him thrown into jail until he should pay the debt.

31 When the other servants saw what had happened, they were very upset and went to the king and told him everything.

32 So he called the servant in. "You worthless slave!' he said. "I forgave you the whole amount you owed me, just because you asked me to.

33 You should have had mercy on your fellow servant, just as I had mercy on you.'

34 The king was very angry, and he sent the servant to jail to be punished until he should pay back the whole amount."
