      9. Then was fulfilled that which was spoken by Jeremy the prophet, saying-- (Zec 11:12, 13). Never was a complicated prophecy, otherwise hopelessly dark, more marvellously fulfilled. Various conjectures have been formed to account for Matthew's ascribing to Jeremiah a prophecy found in the book of Zechariah. But since with this book he was plainly familiar, having quoted one of its most remarkable prophecies of Christ but a few chapters before (Mt 21:4, 5), the question is one more of critical interest than real importance. Perhaps the true explanation is the following, from LIGHTFOOT: "Jeremiah of old had the first place among the prophets, and hereby he comes to be mentioned above all the rest in Mt 16:14; because he stood first in the volume of the prophets (as he proves from the learned DAVID KIMCHI) therefore he is first named. When, therefore, Matthew produceth a text of Zechariah under the name of Jeremy, he only cites the words of the volume of the prophets under his name who stood first in the volume of the prophets. Of which sort is that also of our Saviour (Lu 24:41), 'All things must be fulfilled which are written of Me in the Law, and the Prophets, and the Psalms,' or the Book of Hagiographa, in which the Psalms were placed first."
