Matthew 27:3-5

   3: Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders,
   4: Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that.
   5: And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
