Then the waters shall fail from the sea. He follows out the subject which he had already begun, that the fortifications, by which the Egyptians thought that they were admirably defended, will be of no avail to them. They reckoned themselves to be invincible, because they were surrounded by the sea, and by the Nile, and by fortifications; and historians tell us that it was difficult to gain entrance to them, because the Nile had no mouth, by which they could not easily prevent ships from landing. They therefore boasted that their situation was excellent, and that they were strongly fortified by nature, in like manner as the inhabitants of Venice, at the present day, think that, in consequence of being surrounded by deep ditches, they are impregnable; but fortresses are useless, when God has determined to punish us.

And the waters shall fail - Here commences a description of the "physical" calamities that would come upon the land, which continues to Isaiah 19:10. The previous verses contained an account of the national calamities by civil wars. It may be observed that discord, anarchy, and civil wars, are often connected with physical calamities; as famine, drought, pestilence. God has the elements, as well as the hearts of people, under his control; and when he chastises a nation, he often mingles anarchy, famine, discord, and the pestilence together. Often, too, civil wars have a "tendency" to produce these calamities. They annihilate industry, arrest enterprise, break up plans of commerce, and divert the attention of people from the cultivation of the soil. This might have been in part the case in Egypt; but it would seem also that God, by direct agency, intended to afflict them by drying up their streams in a remarkable manner.
From the sea - The parallelism here, as well as the whole scope of the passage, requires us to understand this of the Nile. The word ים yâm is sometimes used to denote a large river (see the notes at Isaiah 11:15; Isaiah 18:2). The Nile is often called a sea. Thus Pliny ("Nat. Hist." ii. 35) says, 'The water of the Nile resembles the sea.' Thus, Seneca ("Quaest. Nat." v. 2) says, 'By continued accessions of water, it stagnates (stagnat) into the appearance of a broad and turbid sea.' Compare Herodot. ii. 97; Diod. i. 12, 96; 'To this day in Egypt, the Nile is el-Bahr, "the sea," as its most common appellation.' 'Our Egyptian servant,' says Dr. Robinson, 'who spoke English, always called it "the sea."' ("Bib. Rescarches," vol. i. 542).
And the river - The Nile.
Shall be wasted - This does not mean "entirely," but its waters would fail so as to injure the country. It would not "overflow" in its accustomed manner, and the consequence would be, that the land would be desolate. It is well known that Egypt derives its great fertility entirely from the overflowing of the Nile. So important is this, that a public record is made at Cairo of the daily rise of the water. When the Nile rises to a less height than twelve cubits, a famine is the inevitable consequence, for then the water does not overflow the land. When it rises to a greater height than sixteen cubits, a famine is almost as certain - for then the superabundant waters are not drained off soon enough to allow them to sow the seed. The height of the inundation, therefore, that is necessary in order to insure a harvest, is from twelve to sixteen cubits. The annual overflow is in the month of August. The prophet here means that the Nile would not rise to the height that was desirable - or the waters should "fail" - and that the consequence would be a famine.

The river shall be wasted and dried up - The Nile shall not overflow its banks; and if no inundation, the land must become barren. For, as there is little or no rain in Egypt, its fertility depends on the overflowing of the Nile.

And the waters shall (e) fail from the sea, and the rivers shall be wasted and dried up.
(e) He shows that the sea and their great river Nile by which they thought themselves most sure, would not be able to defend them but that he would send the Assyrians among them, that would keep them under as slaves.

And the waters shall fail from the sea,.... Which Kimchi understands figuratively of the destruction of the Egyptians by the king of Assyria, compared to the drying up of the waters of the Nile; and others think that the failure of their trade by sea is meant, which brought great revenues into the kingdom: but, by what follows, it seems best to take the words in a literal sense, of the waters of the river Nile, which being dried up, as in the next clause, could not empty themselves into the sea, as they used, and therefore very properly may be said to fail from it; nay, the Nile itself may be called a sea, it being so large a confluence of water:
and the river shall be wasted and dried up; that is, the river Nile, which was not only very useful for their trade and navigation, but the fruitfulness of the country depended upon it; for the want of rain, in the land of Egypt, was supplied by the overflow of this river, at certain times, which brought and left such a slime upon the earth, as made it exceeding fertile; now the drying up of this river was either occasioned by some great drought, which God in judgment sent; or by the practices of some of their princes with this river, by which it was greatly impaired, and its usefulness diminished.

the sea--the Nile. Physical calamities, it is observed in history, often accompany political convulsions (Ezekiel 30:12). The Nile shall "fail" to rise to its wonted height, the result of which will be barrenness and famine. Its "waters" at the time of the overflow resemble "a sea" [PLINY, Natural History, 85.11]; and it is still called El-Bahr," "the sea," by the Egyptians (Isaiah 18:2; Jeremiah 51:36). A public record is kept at Cairo of the daily rise of the water at the proper time of overflow, namely, August: if it rises to a less height than twelve cubits, it will not overflow the land, and famine must be the result. So, also, when it rises higher than sixteen; for the waters are not drained off in time sufficient to sow the seed.

The prophet then proceeds to foretell another misfortune which was coming upon Egypt: the Nile dries up, and with this the fertility of the land disappears. "And the waters will dry up from the sea, and the river is parched and dried. And the arms of the river spread a stench; the channels of Matzor become shallow and parched: reed and rush shrivel up. The meadows by the Nile, on the border of the Nile, and every corn-field of the Nile, dries up, is scattered, and disappears. And the fishermen groan, and all who throw draw-nets into the Nile lament, and they that spread out the net upon the face of the waters languish away. And the workers of fine combed flax are confounded, and the weavers of cotton fabrics. And the pillars of the land are ground to powder; all that work for wages are troubled in mind." In Isaiah 19:5 the Nile is called yâm (a sea), just as Homer calls it Oceanus, which, as Diodorus observes, was the name given by the natives to the river (Egypt. oham). The White Nile is called bahr el-abyad (the White Sea), the Blue Nile bahr el-azrak, and the combined waters bahr eṅNil, or, in the language of the Besharn, as here in Isaiah, yām. And in the account of the creation, in Genesis 1, yammim is the collective name for great seas and rivers. But the Nile itself is more like an inland sea than a river, from the point at which the great bodies of water brought down by the Blue Nile and the White Nile, which rises a few weeks later, flow together; partly on account of its great breadth, and partly also because of its remaining stagnant throughout the dry season. It is not till the tropical rains commence that the swelling river begins to flow more rapidly, and the yâm becomes a nâhâr. But when, as is here threatened, the Nile sea and Nile river in Upper Egypt sink together and dry up (nisshethu, niphal either of shâthath = nâshattu, to set, to grow shallow; or more probably from nâshath, to dry up, since Isaiah 41:17 and Jeremiah 51:30 warrant the assumption that there was such a verb), the mouths (or arms) of the Nile (nehâr), which flow through the Delta, and the many canals (ye'orim), by which the benefits of the overflow are conveyed to the Nile valley, are turned into stinking puddles (האזניחוּ, a hiphil, half substantive half verbal, unparalleled elsewhere,
(Note: It is not unparalleled as a hiph. denom. (compare הצהיר, oil, יצהר, to press, Job 24:11, Talm. התליע, to become worm-eaten, and many others of a similar kind); and as a mixed form (possibly a mixture of two readings, as Gesenius and Bttcher suppose, though it is not necessarily so), the language admitted of much that was strange, more especially in the vulgar tongue, which found its way here and there into written composition.)
signifying to spread a stench; possibly it may have been used in the place of הזניח, from אזנח or אזנח, stinking, to which a different application was given in ordinary use). In all probability it is not without intention that Isaiah uses the expression Mâtzor, inasmuch as he distinguishes Mâzort from Pathros (Isaiah 11:11), i.e., Lower from Upper Egypt (Egyp. sa-het, the low land, and sa-res, the higher land), the two together being Mitzrayim. And ye'orim (by the side of nehâroth) we are warranted in regarding as the name given of the Nile canals. The canal system in Egypt and the system of irrigation are older than the invasion of the Hyksos (vid., Lepsius, in Herzog's Cyclopaedia). On the other hand, ye'ōr in Isaiah 19:7 (where it is written three times plene, as it is also in Isaiah 19:8) is the Egyptian name of the Nile generally (yaro).
(Note: From the fact that aur in old Egyptian means the Nile, we may explain the Φρουορῶ ἤτοι Νεῖλος, with which the Laterculus of Eratosthenes closes.)
It is repeated emphatically three times, like Mitzrayim in Isaiah 19:1. Parallel to mizra‛, but yet different from it, is ערות, from ערה, to be naked or bare, which signifies, like many derivatives of the synonymous word in Arabic, either open spaces, or as here, grassy tracts by the water-side, i.e., meadows. Even the meadows, which lie close to the water-side (pi = ora, as in Psalm 133:2, not ostium), and all the fields, become so parched, that they blow away like ashes.
Then the three leading sources from which Egypt derived its maintenance all fail: - viz. the fishing; the linen manufacture, which supplied dresses for the priests and bandages for mummies; and the cotton manufacture, by which all who were not priests were supplied with clothes. The Egyptian fishery was very important. In the Berlin Museum there is an Egyptian micmoreth with lead attached. The mode of working the flax by means of serikâh, pectinatio (compare סרוק, wool-combs, Kelim, 12, 2), is shown on the monuments. In the Berlin Museum there are also Egyptian combs of this description with which the flax was carded. The productions of the Egyptian looms were celebrated in antiquity: chōrây, lit., white cloth (singularet. with the old termination ay), is the general name for cotton fabrics, or the different kinds of byssus that were woven there (compare the βυσσίνων ὀθονίων of the Rosetta inscription). All the castes, from the highest to the lowest, are not thrown into agonies of despair. The shâthōth (an epithet that was probably suggested by the thought of shethi, a warp, Syr. 'ashti, to weave, through the natural association of ideas), i.e., the "pillars" of the land (with a suffix relating to Mitzrayim, see at Isaiah 3:8, and construed as a masculine as at Psalm 11:3), were the highest castes, who were the direct supporters of the state edifice; and שׂכר עשׂי cannot mean the citizens engaged in trade, i.e., the middle classes, but such of the people as hired themselves to the employers of labour, and therefore lived upon wages and not upon their own property (שׂכר is used here as in Proverbs 11:18, and not as equivalent to סכר, the dammers-up of the water for the purpose of catching the fish, like סכרין, Kelim, 23, 5).

The waters - Which may be understood either, Metaphorically, of the taking away of their dominion or commerce, &c. or rather, Properly, as may be gathered from the following words. For as the river Nile, when it had a full stream, and free course, did pour forth a vast quantity of waters by its seven famous mouths into the sea, so when that was dried up, which is expressed in the next clause, those waters did truly and properly fail from the sea. So there is no need of understanding by sea either the river Nile, or the great lake of Maeris, which, after the manner of the Hebrews, might be so called. The river - Nile: upon whose fulness and overflow both the safety and the wealth of the land depended; and therefore this was a very terrible judgment. Dried up - Not totally, but in a very great measure.
