From these words we may learn what the Prophet before meant, when he said that the Assyrians were like locusts or chafers; as though he said, -- "I know that you trust in your great number; for ye are like a swarm of chafers or locusts; ye excel greatly in number; inasmuch as you have assembled your merchants and traders as the stars of heaven." Here he shows how numerous they were. But when he says, The chafer has spoiled, and flies away, he points out another reason for the comparison; for it is not enough to lay hold on one clause of the verse, but the two clauses must be connected; and they mean this, -- that the Assyrians, while they were almost innumerable, gloried in their great number, -- and also, that this vast multitude would vanish away. He then makes an admission here and says, by multiplying thy merchants, thou hast multiplied them; but when he says, as chafers and as locusts, he shows that this multitude would not continue, for the Lord would scatter them here and there. As then the scattering was nigh, the Prophet says that they were chafers and locusts. We now understand the design of the Prophet: He first ridicules the foolish confidence with which the Assyrians were inflated. They thought, that as they ruled over many nations, they could raise great armies, and set them in any quarter to oppose any one who might attack them: the Prophet concedes this to them, that is, that they were very numerous, by multiplying thou hast multiplied; but what will this avail them? They shall be locusts, they shall be chafers. -- How so? A fuller explanation follows, Thou hast multiplied thy merchants as the stars of heaven: but this shall be temporary; for thou shalt see them vanishing away very soon; they shall be like the chafers, who, being in a moment scattered here and there, quit the naked field or the meadow. But by merchants or traders some understand confederates; and this comparison also, as we have before seen, frequently occurs in the Prophets: and princes at this day differ nothing from traders, for they outbid one another, and excel in similar artifices, as we have elsewhere seen, by which they carry on a system of mutual deception. This comparison then may be suitable, Thou hast multiplied thy traders, -- tes practiciens. But the meaning of the Prophet may be viewed as still wider; we may apply this to the citizens of Nineveh; for the principal men no doubt were merchants: as the Venetian of the present day are all merchants, so were the Syrians, and the Ninevites, and also the Babylonians. It is then nothing strange, that the Prophet, by taking a part for the whole should include under this term all the rich, Thou hast then multiplied thy merchants [1] He has hitherto allowed them to be very numerous; but he now adds, The chafer has spoiled, and flies away The verb means sometimes to spoil, and it means also to devour: The chafer then has devoured, and flies away; that is, "Thy princes, (as he afterwards calls them,) or thy principal men, have indeed devoured; they have wasted many regions by their plunders, and consumed all things on every side, like the chafers, who destroy the standing corn and all fruits: thou hast then been as a swarm of chafers." For as chafers in great numbers attack a field, so Nineveh was wont to send everywhere her merchants to spoil and to denude the whole land. "Well," he says "the chafer has devoured, but he flies away, he is scattered; so it shall happen," says the Prophet, "to the citizens of Nineveh." And hence he afterwards adds, And thy princes are as locusts: this refers to the wicked doings, by which they laid waste almost the whole earth. As then the locusts and chafers, wherever they come, consume every kind of food, devour all the fields, leave nothing, and the whole land becomes a waste; so also have been thy princes; they have been as locusts and thy leaders as the locusts of locusts, that is, as very great locusts; for this form, we know, expresses the superlative degree in Hebrew. Their leaders were then like the most voracious locusts for the whole land was made barren by them, as nothing was capable of satisfying their avarice and voracity. The Prophet then adds, They are locusts, who dwell in the mounds during the time of cold; but when the sun rises, not known any more is their place He now shows, that it would not be perpetual, that the Ninevites would thus devour the whole earth, and that all countries would be exposed to their voracity; for as the locusts, he says, hide themselves in caverns, and afterwards fly away, so it shall happen to thy princes. But this passage may be taken to mean, -- that the Ninevites concealed themselves in their hiding-places during the winter, and that when the suitable time for plundering came, they retook themselves in different directions, and took possession of various regions, and brought home plunder from the remotest parts. This meaning may be elicited from the words of the Prophet; and the different clauses would thus fitly coalesce together, that when the Ninevites left their nests, they dispersed and migrated in all directions. I do not at the same time disapprove of the former meaning: they are then like locusts, who lodge in mounds during the time of cold; but when the sun rises, -- that is, when the season invites them, (for he speaks not of the winter sun,) but when the heat of the sun prevails and temperate the air, -- then, he says, the locusts go forth and fly away, and known no more is their place He means, in short, that the Ninevites plundered, and that they did so after the manner of locusts; and that a similar end also was nigh them; for the Lord would destroy them, yea, suddenly consume them, so that no trace of them could be found. It follows --

1 - The latter clause of the last verse and this verse and the following are evidently connected. The first, htkvd, hath y added to it in ten or more copies, and may be deemed an imperative as well as the other, and in the feminine gender; Calvin takes it an infinitive. This would be literal rendering -- Increase thyself as the chafer, Increase thyself as the locust, 16. Multiply thy merchants more than the stars of heaven: The chafer spoils, and flies away: 17. Thy crowned ones shall be as the locusts, And thy rulers as the gibbous caterpillar; Which lodge in the fences in the cold day; The sun rises and they flit away, And not known is the place where they are. -- Ed.

Thou hast multiplied thy merchants above the stars of heaven - Not numerous only but glorious in the eyes of the world, and, as thou deemest, safe and inaccessible; yet in an instant all is gone.
The commerce of Nineveh was carried back to prehistoric times, since its rivers bound together the mountains of Armenia with the Persian gulf, and marked out the line, by which the distant members of the human family should supply each others' needs. "Semiramis" they say , "built other cities on the Euphrates and the Tigris, where she placed emporia for those who convey their goods from Media and Paraetacene. Being mighty rivers and passing through a populous country, they yield many advantages to those employed in commerce; so that the places by the river are full of wealthy emporia." The Phoenicians traced back their Assyrian commerce (and as it seems, truly) to those same prehistoric times, in which they alleged, that they themselves migrated from the Persian gulf. They commenced at once, they said , the long voyages, in which they transported the wares of Egypt and Assyria. The building of "Tadmor in the wilderness" 1-Kings 9:18 on the way to Tiphsach (Thapsacus) the utmost bound of Solomon's dominions (1-Kings 5:4 1-Kings 4:24), connected Palestine with that commerce.
The great route for couriers and for traffic, extending for 1,500 or 1,600 miles in later times, must have lain through Nineveh, since, although no mention is made of the city which had perished, the route lay across the two rivers , the greater and lesser Zab, of which the greater formed the Southern limit of Nineveh. Those two rivers led up to two mountain-passes which opened a way to Media and Agbatana; and pillars at the summit of the N. pass attest the use of this route over the Zagros chain about 700 b.c. . Yet a third and easier pass was used by Nineveh, as is evidenced by another monument, of a date as yet undetermined . Two other lines connected Nineveh with Syria and the West. Northern lines led doubtless to Lake Wan and the Black Sea . The lists of plunder or of tribute, carried off during the world-empire of Egypt, before it was displaced by Assyria, attest the extensive imports or manufactures of Nineveh ; the titles of "Assyrian nard, Assyrian amomum, Assyrian odors, myrrh, frankincense , involve its trade with the spice countries: domestic manufactures of hers apparently were purple or dark-blue cloaks, embroidery, brocades, and these conveyed in chests of cedar; her metallurgy was on principles recognized now; in one practical point of combining beauty with strength, she has even been copied .
A line of commerce, so marked out by nature in the history of nations, is not changed, unless some preferable line be discovered. Empires passed away, but, at the end of the 13th century a.d., trade and manufacture continued their accustomed course and habitation. The faith in Jesus had converted the ancient paganism; the heresy of Mohammedanism disputed with the faith for the souls of men; but the old material prosperity of the world held its way. Mankind still wanted the productions of each others' lands. The merchants of Nineveh were to be dispersed and were gone: itself and its remembrance were to be effaced from the earth, and it was so; in vain was a new Nineveh built by the Romans; that also disappeared; but so essential was its possession for the necessities of commerce, that Mosul, a large and populous town, arose over against its mounds, a city of the living over-against its buried glories; and, as our goods are known in China by the name of our great manufacturing capital, so a delicate manufacture imposed on the languages of Europe (Italian, Spanish, French, English, German) the name of Mosul .
Even early in this century, under a mild governor, an important commerce passed through Mosul, from India, Persia, Kurdistan, Syria, Natolia, Europe . And when European traffic took the line of the Isthmus ef Suez, the communication with Kurdistan still secured to it an important and exclusive commerce. The merchants of Nineveh were dispersed and gone. The commerce continued over-against its grave.
The cankerworm spoileth and fleeth away - Better, "the locust hath spread itself abroad (marauded) and is flown." The prophet gives, in three words, the whole history of Nineveh, its beginning and its end. He had before foretold its destruction, though it should be oppressive as the locust; he had spoken of its commercial wealth; he adds to this, that other source of its wealth, its despoiling warfares and their issue. The pagan conqueror rehearsed his victory, "I came, saw, conquered." The prophet goes further, as the issue of all human conquest, "I disappeared." The locust (Nineveh) spread itself abroad (the word is always used of an inroad for plunder , destroying and wasting, everywhere: it left the world a desert, and was gone. Ill-gotten wealth makes one poor, not rich. Truly they who traffic in this world, are more in number than they who, seeking treasure in heaven, shall shine as the stars forever and ever. "For many are called, but few, are chosen." And when all the stars of light "shall abide and praise God Psalm 148:3, these men, though multiplied like the locust, shall, like the locust, pass away, destroying and destroyed. They abide for a while in the chillness of this world; when the Sun of righteousness ariseth, they vanish. This is the very order of God's Providence. As truly as locusts, which in the cold and dew are chilled and stiffened, and cannot spread their wings, fly away when the sun is hot and are found no longer, so shalt thou be dispersed and thy place not anymore be known . It was an earnest of this, when the Assyrians, like locusts, had spread themselves around Jerusalem in a dark day of trouble and of rebuke and of blasphemy Isaiah 37:3, God was entreated and they were not. Midian came up like the grasshopper for multitude Judges 6:4-5; Judges 7:12. In the morning they had fled Judges 7:21. What is the height of the sons of hen? or how do they spread themselves abroad?" At the longest, after a few years it is but as the locust spreads himself and flees away, no more to return.

Thou hast multiplied thy merchants - Like Tyre, this city was a famous resort for merchants; but the multitudes which were there previously to the siege, like the locusts, took the alarm, and fled away.

Thou hast multiplied thy merchants above the stars of heaven,.... A hyperbolical expression, setting forth the great number of merchants that were in Nineveh, and in the land of Assyria; who either were the natives of the place, or came thither for the sake of merchandise, which serve to enrich a nation, and therefore are encouraged to settle; and from whom, in a time of war, much benefit might be expected; being able to furnish with money, which is the sinews of war, as well as to give intelligence of the designs of foreign princes, they trading abroad:
the cankerworm spoileth, and flieth away; or "puts off" (c) its clothes, disrobes and changes its form; or breaks out with force, as the Septuagint, out of its former worm state, and appears a beautiful butterfly, and then flies away. The word is rendered a caterpillar, Psalm 105:34 and what we translate "spoileth" is used of stripping, or putting off of clothes, 1-Samuel 19:24 and the sense may be, that though their merchants were multiplied above the stars of heaven, in which there may be an allusion to the increase of caterpillars, Nahum 3:15 yet, as the caterpillar drops its clothes, and flies away, so their merchants, through fear of the enemy, would depart in haste, or be suddenly stripped of their riches, which make themselves wings, and fly away, Proverbs 23:5. These merchants, at their beginning, might be low and mean, but, increasing, adorning, and enriching themselves in a time of peace, fled away in a time of war: or, "spreads itself" (d), and "flies away"; so these creatures spread themselves on the earth, and devour all they can, and then spread their wings, and are gone; suggesting that in like manner the merchants of Nineveh would serve them; get all they could by merchandise among them, and then betake themselves elsewhere and especially in a time of war, which is prejudicial to merchandise; and hence nothing was to be expected from them, or any dependence had upon them.
(c) "exspoliavit", De Dieu; "proprie est, exuere, vestem detrahere et exspoliare", De Dieu. (d) "Diffundit se", Munster, so the Targum; "effunditur", Cocceius.

multiplied thy merchants-- (Ezekiel 27:23-24). Nineveh, by large canals, had easy access to Babylon; and it was one of the great routes for the people of the west and northwest to that city; lying on the Tigris it had access to the sea. The Phœnicians carried its wares everywhere. Hence its merchandise is so much spoken of.
the cankerworm spoileth, and fleeth away--that is, spoiled thy merchants. The "cankerworm," or licking locust, answers to the Medo-Babylonian invaders of Nineveh [G. V. SMITH]. CALVIN explains less probably, "Thy merchants spoiled many regions; but the same shall befall them as befalls locusts, they in a moment shall be scattered and flee away." MAURER, somewhat similarly, "The licking locust puts off (the envelope in which his wings had been folded), and teeth away" (Nahum 2:9; compare Joel 1:4). The Hebrew has ten different names for the locust, so destructive was it.

The canker - worm spoileth - So these are like the canker - worms, which spoil wherever they come, and when no more is to be gotten, flee away.
