Matthew 27:3-8

3When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse and returned the thirty pieces of silver to the chief priests and the elders.

4“I have sinned,” he said, “for I have betrayed innocent blood.” “What is that to us?” they replied. “That’s your responsibility.”

5So Judas threw the money into the temple and left. Then he went away and hanged himself. 6The chief priests picked up the coins and said, “It is against the law to put this into the treasury, since it is blood money.” 7So they decided to use the money to buy the potter’s field as a burial place for foreigners. 8That is why it has been called the Field of Blood to this day.
