Scripture About Gospel of judas

Then one of the twelve, called Judas Iscariot, went unto the chief priests, And said unto them, What will ye give me, and I will deliver him unto you? And they covenanted with him for thirty pieces of silver. And from that time he sought opportunity to betray him.

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, Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that. And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
