 There is a Talmudic tradition that when the name of a prophet's father is given, the father was also a prophet, so that Amoz would have been a prophet like his son.Though it is mentioned frequently as the patronymic title of Isaiah, the name Amoz appears nowhere else in the Bible.The rabbis of the Talmud declared, based upon a rabbinic tradition, that Amoz was the brother of Amaziah (אמציה), the king of Judah at that time (and, as a result, that Isaiah himself was a member of the royal family).
