Matthew 27:3-5

Then Judas, who betrayed him, when he saw that he was condemned, repented himself, and brought back the thirty pieces of silver to the chief priests and elders, saying, I have sinned in that I betrayed innocent blood. But they said, What is that to us? see thou to it. And he cast down the pieces of silver into the sanctuary, and departed; and he went away and hanged himself.
