Matthew 27:3-10 - The Suicide Of Judas Iscariot
3 Then when Judas, who had betrayed Him, saw that He was condemned, smitten with remorse he brought back the thirty shekels to the High Priests and Elders 4 and said, "I have sinned, in betraying to death one who is innocent." "What does that matter to us?" they replied; it is your business."
5 Flinging the shekels into the Sanctuary he left the place, and went and hanged himself.
6 When the High Priests had gathered up the money they said, "It is illegal to put it into the Treasury, because it is the price of blood." 7 So after consulting together they spent the money in the purchase of the Potter's Field as a burial place for people not belonging to the city; 8 for which reason that piece of ground received the name, which it still bears, of 'the Field of Blood.' 9 Then were fulfilled the words spoken by the Prophet Jeremiah, "And I took the thirty shekels, the price of the prized one on whom Israelites had set a price, 10 and gave them for the potter's field, as the Lord directed me."
