Here is the first of the ten plagues, the turning of the water into blood, which was, 1. A dreadful plague, and very grievous. The very sight of such vast rolling streams of blood, pure blood no doubt, florid and high-colored, could not but strike a horror upon people: much more afflictive were the consequences of it. Nothing more common than water: so wisely has Providence ordered it, and so kindly, that that which is so needful and serviceable to the comfort of human life should be cheap, and almost every where to be had; but now the Egyptians must either drink blood, or die for thirst. Fish was much of their food (Num 11:5), but the changing of the waters was the death of the fish; it was a pestilence in that element (Exo 7:21): The fish died. In the general deluge they escaped, because perhaps they had not then contributed so much to the luxury of man as they have since; but in this particular judgment they perished (Psa 105:29): He slew their fish; and when another destruction of Egypt, long afterwards, is threatened, the disappointment of those that make sluices and ponds for fish is particularly noticed, Isa 19:10. Egypt was a pleasant land, but the noisome stench of dead fish and blood, which by degrees would grow putrid, now rendered it very unpleasant. 2. It was a righteous plague, and justly inflicted upon the Egyptians. For, (1.) Nilus, the river of Egypt, was their idol; they and their land derived so much benefit from it that they served and worshipped it more than the Creator. The true fountain of the Nile being unknown to them, they paid all their devotions to its streams: here therefore God punished them, and turned that into blood which they had turned into a god. Note, That creature which we idolize God justly removes from us, or embitters to us. He makes that a scourge to us which we make a competitor with him. (2.) They had stained the river with the blood of the Hebrews' children, and now God made that river all bloody. Thus he gave them blood to drink, for they were worthy, Rev 16:6. Note, Never any thirsted after blood, but, sooner or later, they had enough of it. 3. It was a significant plague. Egypt had a great dependence upon their river (Zac 14:18), so that in smiting the river they were warned of the destruction of all the productions of their country, till it came at last to their firstborn; and this red river proved a direful omen of the ruin of Pharaoh and all his forces in the Red Sea. This plague of Egypt is alluded to in the prediction of the ruin of the enemies of the New Testament church, Rev 16:3, Rev 16:4. But there the sea, as well as the rivers and fountains of water, is turned into blood; for spiritual judgments reach further, and strike deeper, than temporal judgments do. And, lastly, let me observe in general concerning this plague that one of the first miracles Moses wrought was turning water into blood, but one of the first miracles our Lord Jesus wrought was turning water into wine; for the law was given by Moses, and it was a dispensation of death and terror; but grace and truth, which, like wine, make glad the heart, came by Jesus Christ. Observe,

I.Moses is directed to give Pharaoh warning of this plague. "Pharaoh's heart is hardened (Exo 7:14), therefore go and try what this will do to soften it," Exo 7:15. Moses perhaps may not be admitted into Pharaoh's presence-chamber, or the room of state where he used to give audience to ambassadors; and therefore he is directed to meet him by the river's brink, whither God foresaw he would come in the morning, either for the pleasure of a morning's walk or to pay his morning devotions to the river: for thus all people will walk, every one in the name of his god; they will not fail to worship their god every morning. There Moses must be ready to give him a new summons to surrender, and, in case of a refusal, to tell him of the judgment that was coming upon that very river on the banks of which they were now standing. Notice is thus given him of it beforehand, that they might have no colour to say it was a chance, or to attribute it to any other cause, but that it might appear to be done by the power of the God of the Hebrews, and as a punishment upon him for his obstinacy. Moses is expressly ordered to take the rod with him, that Pharaoh might be alarmed at the sight of that rod which had so lately triumphed over the rods of the magicians. Now learn hence, 1. That the judgments of God are all known to himself beforehand. He knows what he will do in wrath as well as in mercy. Every consumption is a consumption determined, Isa 10:23. 2. That men cannot escape the alarms of God's wrath, because they cannot go out of the hearing of their own consciences: he that made their hearts can make his sword to approach them. 3. That God warns before he wounds; for he is long-suffering, not willing that any should perish, but that all should come to repentance.

II.Aaron (who carried the mace) is directed to summon the plague by smiting the river with his rod, Exo 7:19, Exo 7:20. It was done in the sight of Pharaoh and his attendants; for God's true miracles were not performed, as Satan's lying wonders were, by those that peeped and muttered: truth seeks no corners. An amazing change was immediately wrought; all the waters, not only in the rivers but in all their ponds, were turned into blood. 1. See here the almighty power of God. Every creature is that to us which he makes it to be, water or blood. 2. See the mutability of all things under the sun, and what changes we may meet with in them. That which is water today may be blood tomorrow; what is always vain may soon become vexatious. A river, at the best, is transient; but divine justice can quickly make it malignant. 3. See what mischievous work sin makes. if the things that have been our comforts prove our crosses, we must thank ourselves: it is sin that turns our waters into blood.

III.Pharaoh endeavours to confront the miracle, because he resolves not to humble himself under the plague. He sends for the magicians, and, by God's permission, they ape the miracle with their enchantments (Exo 7:22), and this serves Pharaoh for an excuse not to set his heart to this also (Exo 7:23), and a pitiful excuse it was. Could they have turned the river of blood into water again, this would have been something to the purpose; then they would have proved their power, and Pharaoh would have been obliged to them as his benefactors. But for them, when there was such scarcity of water, to turn more of it into blood, only to show their art, plainly intimates that the design of the devil is only to delude his devotees and amuse them, not to do them any real kindness, but to keep them from doing a real kindness to themselves by repenting and returning to their God.

IV.The Egyptians, in the mean time, are seeking for relief against the plague, digging round about the river for water to drink, Exo 7:24. Probably they found some, with much ado, God remembering mercy in the midst of wrath; for he is full of compassion, and would not let the subjects smart too much for the obstinacy of their prince.

V.The plague continued seven days (Exo 7:25), and, in all that time, Pharaoh's proud heart would not let him so much as desire Moses to intercede for the removal of it. Thus the hypocrites in heart heap up wrath; they cry not when he binds them (Job 36:13); and then no wonder that his anger is not turned away, but his hand is stretched out still.

And the magicians - did so - But if all the water in Egypt was turned into blood by Moses, where did the magicians get the water which they changed into blood? This question is answered in Exo 7:24. The Egyptians dug round about the river for water to drink, and it seems that the water obtained by this means was not bloody like that in the river: on this water therefore the magicians might operate. Again, though a general commission was given to Moses, not only to turn the waters of the river (Nile) into blood, but also those of their streams, rivers, ponds, and pools; yet it seems pretty clear from Exo 7:20 that he did not proceed thus far, at least in the first instance; for it is there stated that only the waters of the river were turned into blood. Afterwards the plague doubtless became general. At the commencement therefore of this plague, the magicians might obtain other water to imitate the miracle; and it would not be difficult for them, by juggling tricks or the assistance of a familiar spirit, (for we must not abandon the possibility of this use), to give it a bloody appearance, a fetid smell, and a bad taste. On either of these grounds there is no contradiction in the Mosaic account, though some have been very studious to find one.

The plague of the bloody waters may be considered as a display of retributive justice against the Egyptians, for the murderous decree which enacted that all the male children of the Israelites should be drowned in that river, the waters of which, so necessary to their support and life, were now rendered not only insalubrious but deadly, by being turned into blood. As it is well known that the Nile was a chief object of Egyptian idolatry, (See Clarke's note on Exo 7:15), and that annually they sacrificed a girl, or as others say, both a boy and a girl, to this river, in gratitude for the benefits received from it, (Universal Hist., vol. i., p. 178, fol. edit)., God might have designed this plague as a punishment for such cruelty: and the contempt poured upon this object of their adoration, by turning its waters into blood, and rendering them fetid and corrupt, must have had a direct tendency to correct their idolatrous notions, and lead them to acknowledge the power and authority of the true God.

And the magicians of Egypt did so with their enchantments,.... Who were either in company with Pharaoh and his nobles, or were immediately sent for to try their art, and confront Moses and Aaron with it; and who very probably got a little water in a vessel, and by some juggling trick imposing upon, and deceiving the sight of Pharaoh and his servants, made it look like blood; and the devil might help them to a sufficient quantity of blood, and discolour the water with it, and make it appear as if it was blood, and which was a poor business; had they turned the bloody river into water again, they would have equalled the miracle of Moses and Aaron, and done some service to their country; but to deceive the sight of people, or to spoil a small quantity of water that was good, by mixing it with blood, was but a mean and unworthy action. Should it be asked from whence they had this water, when all was turned into blood? it may be answered, either from Goshen, as the Targum of Jonathan, the waters of the Hebrews not being affected with this plague: though Aben Ezra thinks they were; or from the sea, as Theodoret; but both these places were too far distant to fetch water from, in the time that Pharaoh stayed here before his return home: rather therefore this water was had from some habitation of the Israelites in the city near at hand, where Pharaoh lived, or was dug for immediately by the magicians, as in Exo 7:24 or it may be that all the waters were not immediately turned into blood, but successively and gradually, first the river, and then its streams, &c. so that there might be near at hand a pool of water, not yet turned into blood, and a vessel of water might be fetched from it, on which they exercised their juggling art:

and Pharaoh's heart was hardened: by seeing his magicians do what was similar to what Moses and Aaron had done; and therefore concluded that it was not by the hand of God, but owing to a magic art they were masters of, as his magicians were:

neither did he hearken unto them; to Moses and Aaron, and what they said to him, to let the people go:

as the Lord had said; had before told he would not hearken to them, Exo 7:4.

And the magicians . . . did so with their enchantments, &c.--Little or no pure water could be procured, and therefore their imitation must have been on a small scale --the only drinkable water available being dug among the sands. It must have been on a sample or specimen of water dyed red with some coloring matter. But it was sufficient to serve as a pretext or command for the king to turn unmoved and go to his house.
