Isaiah 9:11

11.But the Lord will set up the adversaries of Rezin against him. The Israelites having been proud of their alliance with the king of Syria, and hoping that everything would succeed to their wish, Isaiah threatens a new change which will take away all their hope and utterly frustrate their designs, for the Assyrians afterwards took arms and waged war with the Syrians. Accordingly, when Rezin had been slain, (2 Kings 16:9,) that country was entirely ruined. Still more does he heighten this, by adding, he shall mingle; (146) for he means that the Lord will gather together and mingle various enemies whom he will commission to destroy the king of Syria, as the soldiers who composed the army of that vast monarchy were collected out of various nations.
