Matthew 27:3-10 - The Suicide Of Judas Iscariot
3 Then Judas, who betrayed him, when he saw that Jesus was condemned, felt remorse, and returned the thirty pieces of silver to the chief priests and elders, 4 saying, "I have sinned in that I betrayed innocent blood." But they said, "What is that to us? You see to it."
5 He threw down the pieces of silver in the sanctuary, and departed. He went away and hanged himself.
6 The chief priests took the pieces of silver, and said, "It's not lawful to put them into the treasury, since it is the price of blood." 7 They took counsel, and bought the potter's field with them, to bury strangers in. 8 Therefore that field was called "The Field of Blood" to this day. 9 Then that which was spoken through Jeremiah the prophet was fulfilled, saying, "They took the thirty pieces of silver, the price of him upon whom a price had been set, whom some of the sons of Israel priced, 10 and they gave them for the potter's field, as the Lord commanded me."
