(17) And the residue . . .--The Hebrew word is the same as the characteristic "remnant" of Isaiah's earlier prophecies. The words point primarily to the subjugation of Arabia by Sargon and Sennacherib, who narrate their victories over the Arabian tribes (Records of the Past, vii. 34). In Jeremiah 49:28-29 we have an echo of the prediction, which, in that case, pointed to their conquest by Nebuchadnezzar.

21:13-17 The Arabians lived in tents, and kept cattle. A destroying army shall be brought upon them, and make them an easy prey. We know not what straits we may be brought into before we die. Those may know the want of necessary food who now eat bread to the full. Neither the skill of archers, nor the courage of mighty men, can protect from the judgments of God. That is poor glory, which will thus quickly come to nothing. Thus hath the Lord said to me; and no word of his shall fall to the ground. We may be sure the Strength of Israel will not lie. Happy are those only whose riches and glory are out of the reach of invaders; all other prosperity will speedily pass away.And the residue of the number of archers,.... Or of "bow" (g), for "bows": that is, of men that use the bow, or are expert at it, as the Kedarenes were, both for taking wild beasts, and fighting with men, in which they followed their original ancestor Ishmael, Genesis 21:20 the number of these archers it seems had been great, but would be lessened by the calamity threatened; and those that would escape that, and be preserved from it, should be lessened still, as follows:

the mighty men of the children of Kedar shall be diminished; their military men, the most expert at the use of the bow, and the most valiant and courageous; the few of those that were left, and did not fall by the sword of the Assyrians, should gradually diminish, and be fewer and fewer:

for the Lord God of Israel hath spoken it; who cannot lie, nor will repent, and whose word never fails, what he has said he will do, nor will he alter the thing that is gone out of his lips; and he is spoken of as the God of Israel, because it was to the Israelites that this was said, and for their sakes; either because these Arabians some way or other were injurious to them, or they had put some confidence in them. The Targum is,

"because by the word of the Lord God of Israel it is so decreed.''
