THE FIRST PLAGUE.

(14-21) The water turned to blood.--Moses had already been empowered to turn water into blood on a small scale (Exodus 4:9), and had exhibited his power before his own people (Exodus 4:30). But the present miracle is different. (1) It is to be done on the largest possible scale; (2) in the sight of all the Egyptians; and (3) not as a sign, but as a "judgment." All the Nile water--whether in the main river, or its branches, or the canals derived from it, or the pools formed by its inundation or by percolation through its banks, or in artificial reservoirs, including the tanks of wood or stone attached to houses (Exodus 7:19)--is to be "turned to blood:" i.e., not merely turned of a red colour, either by admixture of earthy matter or of Infusoriae, but made to have all the qualities and appearance of blood, so as to become offensive, horrible, loathsome (Exodus 7:18). The judgment strikes the Egyptians two several blows. (1) It involves an insult to their religion, and brings it into discredit, since the Nile-god, Hapi, was a main object of worship, closely connected with Osiris, and even with Amnion, celebrated in hymns with the most extravagant titles of honour (Records of the Past, vol. iv. pp. 108-110), and a frequent object of public adoration in festivals. (2) It is a great physical affliction. They are accustomed to use the Nile water for drinking, for ablutions, for the washing of their clothes, and for culinary purposes; they have great difficulty in procuring any other; they delight in the Nile water, regard it as the best in the world, are in the habit of drinking deep draughts of it continually. This is all put a stop to. They suffer from thirst, from enforced uncleanliness, from the horror of blood all about them, even in their cisterns. Again, their fish are killed. Fish was one of their principal foods, perhaps the main food of the common people; and the river was the chief source whence the fish supply was obtained, for even the Lake Moeris was an off-shoot from the river (Herod. ii. 149). Their fish supply is stopped. The punishment is retaliatory: for as they had made the Nile the means of destroying Hebrew infants (Exodus 1:22), so that Hebrew parents had loathed to drink of it, as though stained with the blood of their children, so is it now made by means of blood undrinkable for themselves. The plague lasts seven days (Exodus 7:25), a longer time than any other; and if not so destructive as the later ones, was perhaps of all the most nauseous and disgusting.

Verses 14-21. - THE FIRST PLAGUE. The first miracle had been exhibited, and had failed. It had been a mere "sign," and in no respect a "judgment." Now the "judgments ' were to begin. God manifests himself again to Moses, and gives him exact directions what he is to do. He is to meet Pharaoh on the banks of the Nile, and to warn him that a plague is coming upon all Egypt on account of his obstinacy; that the waters of the Nile will be turned to blood, so that the ash will die, and the river stink, and the Egyptians loathe to drink of the water of the river (vers. 15-18). Pharaoh not yielding, making no sign, the threat is to be immediately followed by the act. In the sight of Pharaoh and his court, or at any rate of his train of attendants (ver. 20), Aaron is to stretch his rod over the Nile, and the water is at once to become blood, the fish to die, and the river in a short time to become offensive, or, in the simple and direct language of the Bible, to stink. The commands given by God are executed, and the result is as declared beforehand by Moses (vers. 20, 21). Verse 14. - Pharaoh's heart is hardened. Rather, "is hard, is dull." The adjective used is entirely unconnected with the verb of the preceding verse.

7:14-25 Here is the first of the ten plagues, the turning of the water into blood. It was a dreadful plague. The sight of such vast rolling streams of blood could not but strike horror. Nothing is more common than water: so wisely has Providence ordered it, and so kindly, that what 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. Egypt was a pleasant land, but the dead fish and blood now rendered it very unpleasant. It was a righteous plague, and justly sent upon the Egyptians; for Nile, the river of Egypt, was their idol. That creature which we idolize, God justly takes from us, or makes bitter to us. They had stained the river with the blood of the Hebrews' children, and now God made that river all blood. Never any thirsted after blood, but sooner or later they had enough of it. It was a significant plague; Egypt had great dependence upon their river, Zec 14:18; so that in smiting the river, they were warned of the destruction of all the produce of their country. The love of Christ to his disciples changes all their common mercies into spiritual blessings; the anger of God towards his enemies, renders their most valued advantages a curse and a misery to them. Aaron is to summon the plague by smiting the river with his rod. It was done in the sight of Pharaoh and his attendants, for God's true miracles were not performed as Satan's lying wonders; truth seeks no corners. See the almighty power of God. Every creature is that to us which he makes it to be water or blood. See what changes we may meet with in the things of this world; what is always vain, may soon become vexatious. 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. The plague continued seven days; and in all that time Pharaoh's proud heart would not let him desire Moses to pray for the removal of it. Thus the hypocrites in heart heap up wrath. No wonder that God's anger is not turned away, but that his hand is stretched out still.And the Lord said unto Moses, Pharaoh's heart is hardened,.... Or "heavy" (c), dull and stupid, stiff and inflexible, cannot lift up his heart, or find in his heart to obey the will of God:

he refuseth to let the people go; which was an instance and proof of the hardness and heaviness of his heart, on which the above miracle had made no impression, to regard what God by his ambassadors had required of him.
