Matthew 27:3-5

3Then Judas, who had betrayed him, when he saw that he was condemned, repented, and brought again the thirty pieces of silver to the chief priests and elders,

4Saying, I have sinned in that I have betrayed innocent blood. And they said, What is that to us? see thou to that .

5And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
