Lessons from Judas
Early in the morning, all the head cohanim (priests) and elders met to plan how to bring about Yeshua’s death. 2 Then they put him in chains, led him away and handed him over to Pilate the governor.
3 When Y’hudah (Judas), who had betrayed him, saw that Yeshua had been condemned, he was seized with remorse and returned the thirty silver coins to the head cohanim and elders, 4 saying, “I sinned in betraying an innocent man to death.” “What is that to us?” they answered. “That’s your problem.” 5 Hurling the pieces of silver into the sanctuary, he left; then he went off and hanged himself.
6 The head cohanim took the silver coins and said, “It is prohibited to put this into the Temple treasury, because it is blood money.” 7 So they decided to use it to buy the potter’s field as a cemetery for foreigners. 8 This is how it came to be called the Field of Blood, a name it still bears. 9 Then what Yirmeyahu (Jeremiah) the prophet spoke was fulfilled, “And they took the thirty silver coins, which was the price the people of Isra’el had agreed to pay for him, 10 and used them to buy the potter’s field, just as the Lord directed me.”
12 I said to them, “If it seems good to you, give me my wages; if not, don’t.” So they weighed out my wages, thirty silver [shekels, that is, twelve ounces]. 13 Concerning that “princely sum” at which they valued me, Adonai said, “Throw it into the treasury!” So I took the thirty silver [shekels] and threw them into the treasury in the house of Adonai.
Confusion... In this passage it says that what "Jeremiah the prophet spoke was fulfilled." However, the reference in the writings of the Prophets came from Zechariah. I was confused. I found this article to bring some clarification to this issue. Click the link for a better understanding than me trying to write it all out again.
