Jeremy: The words here quoted are not found in Jeremiah, but in Zechariah; and a variety of conjectures have been formed, in order to reconcile this discrepancy. The most probable opinion seems to be, that the name of the prophet was originally omitted by the Evangelist, and that the name of Jeremiah was added by some subsequent copyist. It is omitted in two manuscripts of the twelfth century, in the Syriac, later Persic, two of the Itala, and in some other Latin copies; and what renders it highly probable that the original reading was δια: strong:G1223, του: strong:G5120, προφητον:, by the prophet, is, that Matthew frequently omits the name of the prophet in his quotations. See note on Matthew 1:22; Matthew 2:5, Matthew 2:15; Matthew 13:35; Matthew 21:4. This omission is approved of by Bengel, Dr. A. Clarke, and Horne.
