Matthew 27:3-5

3Now when Judas, who had betrayed him, saw that Jesus had been condemned, he regretted what he had done and returned the thirty silver coins to the chief priests and the elders,

4saying, “I have sinned by betraying innocent blood!” But they said, “What is that to us? You take care of it yourself!”

5So Judas threw the silver coins into the temple and left. Then he went out and hanged himself.
