1 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The LORD hath not appeared unto thee.   2 And the LORD said unto him, What is that in thine hand? And he said, A rod.   3 And he said, Cast it on the ground. And he cast it on the ground, and it became a serpent; and Moses fled from before it.   4 And the LORD said unto Moses, Put forth thine hand, and take it by the tail. And he put forth his hand, and caught it, and it became a rod in his hand:   5 That they may believe that the LORD God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee.   6 And the LORD said furthermore unto him, Put now thine hand into thy bosom. And he put his hand into his bosom: and when he took it out, behold, his hand was leprous as snow.   7 And he said, Put thine hand into thy bosom again. And he put his hand into his bosom again; and plucked it out of his bosom, and, behold, it was turned again as his other flesh.   8 And it shall come to pass, if they will not believe thee, neither hearken to the voice of the first sign, that they will believe the voice of the latter sign.   9 And it shall come to pass, if they will not believe also these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river shall become blood upon the dry land.

      It was a very great honour that Moses was called to when God commissioned him to bring Israel out of Egypt; yet he is with difficulty persuaded to accept the commission, and does it at last with great reluctance, which we should rather impute to a humble diffidence of himself and his own sufficiency than to any unbelieving distrust of God and his word and power. Note, Those whom God designs for preferment he clothes with humility; the most fit for service are the least forward.

      I. Moses objects that in all probability the people would not hearken to his voice (v. 1), that is, they would not take his bare word, unless he showed them some sign, which he had not been yet instructed to do. This objection cannot be justified, because it contradicts what God had said (ch. iii. 18), They shall hearken to thy voice. If God says, They will, does it become Moses to say, They will not? Surely he means, "Perhaps they will not at first, or some of them will not." If there should be some gainsayers among them who would question his commission, how should he deal with them? And what course should he take to convince them? He remembered how they had once rejected him, and feared it would be so again. Note, 1. Present discouragements often arise from former disappointments. 2. Wise and good men have sometimes a worse opinion of people than they deserve. Moses sad (v. 1), They will not believe me; and yet he was happily mistaken, for it is said (v. 31), The people believed; but then the signs which God appointed in answer to this objection were first wrought in their sight.

      II. God empowers him to work miracles, directs him to three particularly, two of which were now immediately wrought for his own satisfaction. Note, True miracles are the most convincing external proofs of a divine mission attested by them. Therefore our Saviour often appealed to his works (as John v. 36), and Nicodemus owns himself convinced by them, John iii. 2. And here Moses, having a special commission given him as a judge and lawgiver to Israel, has this seal affixed to his commission, and comes supported by these credentials.

      1. The rod in his hand is made the subject of a miracle, a double miracle: it is but thrown out of his hand and it becomes a serpent; he resumes it and it becomes a rod again, v. 2-4. Now, (1.) Here was a divine power manifested in the change itself, that a dry stick should be turned into a living serpent, a lively one, so formidable a one that Moses himself, on whom, it should seem, it turned in some threatening manner, fled from before it, though we may suppose, in that desert, serpents were no strange things to him; but what was produced miraculously was always the best and strongest of the kind, as the water turned to wine: and, then, that this living serpent should be turned into a dry stick again, this was the Lord's doing. (2.) Here was an honour put upon Moses, that this change was wrought upon his throwing it down and taking it up, without any spell, or charm, or incantation: his being empowered thus to act under God, out of the common course of nature and providence, was a demonstration of his authority, under God, to settle a new dispensation of the kingdom of grace. We cannot imagine that the God of truth would delegate such a power as this to an impostor. (3.) There was a significancy in the miracle itself. Pharaoh had turned the rod of Israel into a serpent, representing them as dangerous (ch. i. 10), causing their belly to cleave to the dust, and seeking their ruin; but now they should be turned into a rod again: or, thus Pharaoh had turned the rod of government into the serpent of oppression, from which Moses had himself fled into Midian; but by the agency of Moses the scene was altered again. (4.) There was a direct tendency in it to convince the children of Israel that Moses was indeed sent of God to do what he did, v. 5. Miracles were for signs to those that believed not, 1 Cor. xiv. 22.

      2. His hand itself is next made the subject of a miracle. He puts it once into his bosom, and takes it out leprous; he puts it again into the same place, and takes it out well, v. 6, 7. This signified, (1.) That Moses, by the power of God, should bring sore diseases upon Egypt, and that, at his prayer, they should be removed. (2.) That whereas the Israelites in Egypt had become leprous, polluted by sin, and almost consumed by oppression (a leper is as one dead, Num. xii. 12), by being taken into the bosom of Moses they should be cleansed and cured, and have all their grievances redressed. (3.) That Moses was not to work miracles by his own power, nor for his own praise, but by the power of God and for his glory; the leprous hand of Moses does forever exclude boasting. Now it was supposed that, if the former sign did not convince, this latter would. Note, God is willing more abundantly to show the truth of his word, and is not sparing in his proofs; the multitude and variety of the miracles corroborate the evidence.

      3. He is directed, when he shall come to Egypt, to turn some of the water of the river into blood, v. 9. This was done, at first, as a sign, but, not gaining due credit with Pharaoh, the whole river was afterwards turned into blood, and then it became a plague. He is ordered to work this miracle in case they would not be convinced by the other two. Note, Unbelief shall be left inexcusable, and convicted of a wilful obstinacy. As to the people of Israel, God had said (ch. iii. 18), They shall hearken; yet he appoints these miracles to be wrought for their conviction, for he that has ordained the end has ordained the means.

      14 And the LORD said unto Moses, Pharaoh's heart is hardened, he refuseth to let the people go.   15 Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river's brink against he come; and the rod which was turned to a serpent shalt thou take in thine hand.   16 And thou shalt say unto him, The LORD God of the Hebrews hath sent me unto thee, saying, Let my people go, that they may serve me in the wilderness: and, behold, hitherto thou wouldest not hear.   17 Thus saith the LORD, In this thou shalt know that I am the LORD: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood.   18 And the fish that is in the river shall die, and the river shall stink; and the Egyptians shall loathe to drink of the water of the river.   19 And the LORD spake unto Moses, Say unto Aaron, Take thy rod, and stretch out thine hand upon the waters of Egypt, upon their streams, upon their rivers, and upon their ponds, and upon all their pools of water, that they may become blood; and that there may be blood throughout all the land of Egypt, both in vessels of wood, and in vessels of stone.   20 And Moses and Aaron did so, as the LORD commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood.   21 And the fish that was in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt.   22 And the magicians of Egypt did so with their enchantments: and Pharaoh's heart was hardened, neither did he hearken unto them; as the LORD had said.   23 And Pharaoh turned and went into his house, neither did he set his heart to this also.   24 And all the Egyptians digged round about the river for water to drink; for they could not drink of the water of the river.   25 And seven days were fulfilled, after that the LORD had smitten the river.

      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. xi. 5), but the changing of the waters was the death of the fish; it was a pestilence in that element (v. 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 (Ps. cv. 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. xix. 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. xvi. 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 (Zech. xiv. 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. xvi. 3, 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 (v. 14), therefore go and try what this will do to soften it," v. 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. x. 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, v. 19, 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 to-day may be blood to-morrow; 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 (v. 22), and this serves Pharaoh for an excuse not to set his heart to this also (v. 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, v. 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 (v. 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 xxxvi. 13); and then no wonder that his anger is not turned away, but his hand is stretched out still.
