 This identification can be reconciled if Jehoiada was Zechariah's grandfather, and Berechiah his father.However, the prophet Zechariah is listed as the son of Berechiah () and some therefore make this identification.The Book of Zechariah is commonly dated to c. 520-518 BC, several hundred years after the reign of Jehoash of Judah, and in this interpretation Zechariah is chronologically the last of the martyrs.
