Thirty pieces of silver was the price for which Judas Iscariot betrayed Jesus, according to an account in the Gospel of Matthew 26:15 in the New Testament.[1] Before the Last Supper, Judas is said to have gone to the chief priests and agreed to hand over Jesus in exchange for 30 silver coins and to have attempted to return the money afterwards, filled with remorse.
The Gospel of Matthew claims that the subsequent purchase of the potter's field was fulfilment by Jesus of a prophecy of Zechariah.[2][3]
