Matthew 18:28-31

The reaction of the forgiven servant was appalling. He proceeded to try to collect a debt from a fellow slave and even resorted to physical violence to obtain it. A denarius was a day’s wage for a common laborer or a foot soldier. [Note: Tobit 5:14; Tacitus Annales 1:17.] Therefore the debt owed was substantial, but compared with the debt the king had forgiven the creditor servant it was trivial.

Both debtors appealed to their respective creditors similarly (Matthew 18:26; Matthew 18:29). Yet the servant creditor remained unmoved, hardhearted. He threw his fellow servant into the debtor’s prison until he could extract the full amount of his debt from him. Other servants of the king, who were aware of the situation and deeply distressed by it, reported everything to their lord "in detail" (Gr. diesaphesan).
