(16) According to the years of an hireling . . . The prophet uses, as in Isaiah 16:14, the formula which expressed the most precise measurement, and so gives a test as to his forecast of the future.

And all the glory of Kedar shall fail.--Kedar is used, as in Psalm 120:5, Song of Solomon 1:5, generically for the nomadic tribes of Arabia, including Dedan.

Verse 16. - Within a year, according to the years of an hireling (see the comment on Isaiah 16:14). All the glory of Kedar shall fail. "Kedar" is a name of greater note than either Dedan or Tome. It seems to be used here as inclusive of Dedan, perhaps as a designation of the northern Arabians generally. The people of Kedar, like those of Dedan, carried on trade with Tyro (Ezekiel 27:21). They dwelt partly in tents (Psalm 120:5; Jeremiah 49:29), partly in villages (Isaiah 42:11), and were rich in flocks and herds and in camels. Though not mentioned in the inscriptions of Sargon, Sennacherib, or Esarhaddon, the contemporaries of Isaiah, they hold a prominent place in those of Esarhaddon's son and successor, Asshurbanipal, with whom they carried on a war of some considerable duration in conjunction with the Nabathaeans (G. Smith, 'History of Asshur-bani-pal,' pp. 261-290).

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.For thus hath the Lord said unto me,.... The prophet; which confirms what is before said, as well as assures the accomplishment of what follows:

within a year, according to the years of an hireling; that is, exactly and precisely, as soon as ever the year is come to an end; for the hireling, when his year is up, instantly demands dismissal from his service, or his wages, or both. The time is to be reckoned from the delivery of this prophecy; and so the calamity predicted was brought upon them by the Assyrians, perhaps under Sennacherib, when he invaded the cities of Judah, and might take Arabia in his way; less time is allowed than was the Moabites, who suffered by the same hand; see Isaiah 16:14,

and all the glory of Kedar shall fail; these were another sort of Arabians, as the Targum calls them: they descended from Kedar, a son of Ishmael, Genesis 25:13 their "glory" were their multitude, their riches and substance, and which chiefly lay in their flocks; for the sake of which they moved from place to place for pasture, and dwelled in tents, which they carried with them, and pitched where it was most convenient for them; hence they were called Scenites; see Psalm 120:5.
