Commentaries
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.

sword, not of … mighty … mean man—but by the unseen sword of God.
flee—Sennacherib alone fled homewards after his army had been destroyed (Isa 37:37).
young men—the flower of his army.
discomfited—rather, "shall be subject to slavery"; literally, "shall be liable to tribute," that is, personal service (De 20:11; Jos 9:21) [Maurer]. Or, not so well, "shall melt away" [Rosenmuller].
