Verse 17. - They that were his arm. The words point to the allies, in the first instance of Assyria, and secondly of Egypt. The last words of the verse present a striking parallel to Lamentations 4:20.

31:10-18 The king of Egypt resembled the king of Assyria in his greatness: here we see he resembles him in his pride. And he shall resemble him in his fall. His own sin brings his ruin. None of our comforts are ever lost, but what have been a thousand times forfeited. When great men fall, many fall with them, as many have fallen before them. The fall of proud men is for warning to others, to keep them humble. See how low Pharaoh lies; and see what all his pomp and pride are come to. It is best to be a lowly tree of righteousness, yielding fruit to the glory of God, and to the good of men. The wicked man is often seen flourishing like the cedar, and spreading like the green bay tree, but he soon passes away, and his place is no more found. Let us then mark the perfect man, and behold the upright, for the end of that man is peace.They also went down to hell with him,.... To the grave with him; many of his nobles, princes, generals, soldiers, and subjects:

unto them that be slain with the sword; to be buried and lie with them who had fallen by the sword, as a just punishment for their iniquities:

and they that were his arm; either that leaned on his arm, were dependents upon him; or his ministers, his instruments, whom he employed under him as his deputies, to govern the several provinces that belonged to him; or rather his allies and auxiliaries, who helped and assisted him on occasion:

that dwelt under his shadow in the midst of the Heathen; in the midst of the nations subject to the Assyrian empire; such who put themselves under the protection of it, lived comfortably under it, and continued with it to the last; these shared the same fate as that did. The Targum is,

"his governors are broken, whom he strengthened in the midst of the kingdom.''
