Matthew 27:3-5 (New International Version)

 ³When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse and returned the thirty silver coins 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.
