One of the great Hebrew prophets, the son of one Amoz; was a citizen of Jerusalem, evidently of some standing, and who flourished between 750 and 700 B.C.; like Amos (q. v .), he foresaw the judgment that was coming on the nation for its unfaithfulness, but felt assured that God would not altogether forsake His people, and that "a remnant," God's elect among them, would be saved—that though the casket would be shat tered in pieces, the jewel it contained would be preserved.
