Isaiah 8:4

Before the boy grew old enough to speak distinctly, Assyria (Tiglath-pileser III) would carry off the wealth of Damascus and Samaria (in 732 B.C.; cf. Isaiah 7:15-16; 2 Kings 15:29). This brought to a close a 200-year period in which the Aramean Kingdom played a leading role. [Note: Watts, p. 114.] Thus Syria and Israel would not only fail in their attempt to bring Judah under their power (cf. Isaiah 7:6), but the king of Assyria would bring them under his power. This second promise is almost identical to the earlier one in Isaiah 7:4-9. Perhaps God intended it to be a second witness to the truthfulness of His Word.
