6 Turn unto him from whom ye have deeply revolted, ye children of Israel; 7 for in that day every man shall cast away his idols of silver and his idols of gold, which your sinful hands have made unto you. 8 And Asshur shall fall by the sword, not of a great man; and the sword, not of a mean man, shall devour him: and he shall flee from the sword, and his young men shall become tributary; 9 and for fear, he shall pass over to his rock, and his princes shall be afraid of the banner, saith Jehovah, whose fire is in Zion, and his furnace in Jerusalem.

Matthew Henry's Commentary on Isaiah 31:6-9

Commentary on Isaiah 31:6-9

(Read Isaiah 31:6-9)

They have been backsliding children, yet children; let them return, and their backslidings shall be healed, though they have sunk deep into misery, and cannot easily recover. Many make an idol of their silver and gold, and by the love of that are drawn from God; but those who turn to God, will be ready to part with it. Then, when they have cast away their idols, shall the Assyrian fall by the sword of an angel, who strikes more strongly than a mighty man, yet more secretly than a mean man. God can make the stoutest heart to tremble. But if we keep up the fire of holy love and devotion in our hearts and houses, we may depend upon God to protect us and them.
