Zechariah, the eleventh of the twelve minor prophets, was son of Berechiah, and grandson of Iddo. He returned from Babylon with Zerubbabel: and began to prophesy in the second year of the reign of Darius, son of Hystaspes, in the year of the world 3484; before Christ, 516; before the vulgar era, 520; in the eighth month of the holy year; and two months after Haggai had begun to prophesy.
These two prophets, with united zeal, encouraged at the same time the people to go on with the work of the temple, which had been discontinued for some years.
The time and place of the birth of Zechariah are unknown. Some will have him to have been born at Babylon, during the captivity; others think he was born at Jerusalem, before the tribes of Judah and Benjamin were carried away. Some maintain that he was a priest; but others affirm that he was no priest. Many say he was the immediate son of Iddo; others believe, with much more reason, that he was son of Berechiah, and grandson of Iddo.
He has been confounded with one Zechariah, the son of Barachiah, who lived in the time of Isaiah; and with Zechariah, the father of John the Baptist; which opinion is plainly incongruous. Lastly, he has been thought to be Zechariah the son of Barachiah, whom our Savior mentions, and says he was killed between the temple and the altar; though no such thing is anywhere said of our prophet. A tomb is shown to this day at the foot of the Mount of Olives, which, it is pretended, belongs to the prophet Zechariah. Dorotheus maintains that he was buried in a place called Bethariah, one hundred and fifty furlongs from Jerusalem.
Zechariah is the longest and the most obscure of all the twelve minor prophets. His style is interrupted, and without connection. His prophecies concerning the Messiah are more particular and express than those of the other prophets. Some modern critics, as Mede and Hammond, have been of opinion that the ninth, tenth, and eleventh chapters of this prophet were written by Jeremiah; because in Matthew,Mat 27:9, Mat 27:10, under the name of Jeremiah, we find quoted Zechariah; (Zec 11:12); and as the aforesaid chapters make but one continued discourse, they concluded from thence that all three belonged to Jeremiah. But it is much more natural to suppose that, by some unlucky mistake, the name of Jeremiah has slipped into the text of St. Matthew instead of that of Zechariah.
