VI. Egypt was famous for its river Nile, which was its wealth, and strength, and beauty, and was idolized by them. Now it is here threatened that the waters shall fail from the sea and the river shall be wasted and dried up, v. 5. Nature shall not herein favour them as she has done. Egypt was never watered with the rain of heaven (Zech. xiv. 18), and therefore the fruitfulness of their country depended wholly upon the overflowing of their river; if that therefore be dried up, their fruitful land will soon be turned into barrenness and their harvests cease: Every thing sown by the brooks will wither of course, will be driven away, and be no more, v. 7. If the paper-reeds by the brooks, at the very mouth of them, wither, much more the corn, which lies at a greater distance, but derives its moisture from them. Yet this is not all; the drying up of their rivers is the destruction, 1. Of their fortifications, for they are brooks of defence (v. 6), making the country difficult of access to an enemy. Deep rivers are the strongest lines, and most hardly forced. Pharaoh is said to be a great dragon lying in the midst of his rivers, and guarded by them, bidding defiance to all about him, Ezek. xxix. 3. But these shall be emptied and dried up, not by an enemy, as Sennacherib with the sole of his foot dried up mighty rivers (ch. xxxvii. 25), and as Cyrus, who took Babylon by drawing Euphrates into many streams, but by the providence of God, which sometimes turns water-springs into dry ground, Ps. cvii. 33. 2. It is the destruction of their fish, which in Egypt was much of their food, witness that base reflection which the children of Israel made (Num. xi. 5): We remember the fish which we did eat in Egypt freely. The drying up of the rivers will kill the fish (Ps. cv. 29), and will thereby ruin those who make it their business, (1.) To catch fish, whether by angling or nets (v. 8); they shall lament and languish, for their trade is at an end. There is nothing which the children of this world do more heartily lament than the loss of that which they used to get money by. Ploratur lachrymis amissa pecunia veris—Those are genuine tears which are shed over lost money. (2.) To keep fish, that it may be ready when it is called for. There were those that made sluices and ponds for fish (v. 10), but they shall be broken in the purposes thereof; their business will fail, either for want of water to fill their ponds or for want of fish to replenish their waters. God can find ways to deprive a country even of that which is its staple commodity. The Egyptians may themselves remember the fish they have formerly eaten freely, but now cannot have for money. And that which aggravates the loss of these advantages by the river is that it is their own doing (v. 6): They shall turn the rivers far away. Their kings and great men, to gratify their own fancy, will drain water from the main river to their own houses and grounds at a distance, preferring their private convenience before the public good, and so by degrees the force of the river is sensibly weakened. Thus many do themselves a greater prejudice at last than they think of, [1.] Who pretend to be wiser than nature, and to do better for themselves than nature has done. [2.] Who consult their own particular interest more than the common good. Such may gratify themselves, but surely they can never satisfy themselves, who to serve a turn contribute to a public calamity, which they themselves, in the long run, cannot avoid sharing in. Herodotus tells us that Pharaoh-Necho (who reigned not long after this), projecting to cut a free passage by water from Nilus into the Red Sea, employed a vast number of men to make a ditch or channel for that purpose, in which attempt he impaired the river, lost 120,000 of his people, and yet left the work unaccomplished.
