ZACHARIAH. KJV alternate form of Zechariah.
International Standard Bible Encyclopedia (1915)
(Zacharias; the, Zacharias):
(1) The son of Barachiah, who, Jesus says, was slain between the temple and the altar (Mt 23:35; Lu 11:51). The allusion seems to be to the murder of Zechariah, the son of Jehoiada (2Ch 24:20 ). In this case "Barachiah" would seem to be a gloss which has crept into the text through confusion with the name of the father of the prophet Zechariah, BERECHIAH (which see).
(2) See Zechariah.
