John 19:28-30. In ancient times, those who committed crimes not worthy of death might be fined heavily. If they were unable to pay the debt, they would be placed in prison. They would be given a hand-bill that stated the nature of their crime, and the days, months, and years of their sentence. Should someone have pity on them  and pay their debt, the authorities would free them from prison, writing on the hand-bill “tetelestai” – it has ended.  If anyone questioned why the man was free, he need only present the handbill to show that the debt had been paid.
The last word Jesus said was “tetelestai.”

LORD, Thank you for paying the debt of our sins. Because of your grace, the sentence has ended.
