Matthew 27:3-5

3 When Judas, his betrayer, saw that he was condemned, he repented and brought back the thirty pieces of silver to the chief priests and the elders,

4 saying, "I have sinned in betraying innocent blood." They said, "What is that to us? See to it yourself."

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