Matthew 26:15
And said: what will you give me if I deliver him over to you? And they paid him thirty pieces of silver. The commercial character of the betrayal: what will you give me. The thirty pieces of silver — the price of a slave gored by an ox in Exodus 21:32, and the fulfillment of Zechariah 11:12–13 (they weighed out thirty pieces of silver as my wages) — is the price the chief priests agreed on. The temple authorities paid the price of a slave for the one they would crucify.
