“Then was fulfilled that which was spoken by Jeremy the prophet, saying, And they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value;”
King James Version (KJV)
27:9 Then was fulfilled - What was figuratively represented of old, was now really accomplished. What was spoken by the prophet - The word Jeremy, which was added to the text in latter copies, and thence received into many translations, is evidently a mistake: for he who spoke what St. Matthew here cites (or rather paraphrases) was not Jeremy, but Zechariah. #Zech 11:12|.
Mt 27:9 Then was fulfilled. The prophecy is found in Zec 11:12. Albert Barnes shows that a change of a single letter in the original would transform Zechariah into Jeremiah, and it is supposed that some early copyist made the mistake. Another explanation is that Jeremiah, in the Jewish arrangement of the prophets, stood first, and that his name was given to the whole book of prophecy.
