Yahweh will bring on you, on your people and on your father’s house, days that have not come from the day that Ephraim separated from Judah—the king of Assyria. Bible see other translations

“Ephraim separated from Judah.” The United Kingdom of Israel that was established and ruled by Saul, then David, then Solomon, split into the two kingdoms of Israel and Judah after the death of Solomon (c. 940 BC; 1 Kings 12). Since Isaiah gave this prophecy to king Ahaz, it was during his reign and thus between 740 and 726 BC.
