The first time that Moses made his application to Pharaoh, he produced his instructions only; now he is directed to produce his credentials, and does accordingly. 1. It is taken for granted that Pharaoh would challenge these demandants to work a miracle, that, by a performance evidently above the power of nature, they might prove their commission from the God of nature. Pharaoh will say, Show a miracle; not with any desire to be convinced, but with the hope that none will be wrought, and then he would have some colour for his infidelity. 2. Orders are therefore given to turn the rod into a serpent, according to the instructions, Exo 4:3. The same rod that was to give the signal of the other miracles is now itself the subject of a miracle, to put a reputation upon it. Aaron cast his rod to the ground, and instantly it became a serpent, Exo 7:10. This was proper, not only to affect Pharaoh with wonder, but to strike a terror upon him. Serpents are hurtful dreadful animals; the very sight of one, thus miraculously produced, might have softened his heart into a fear of that God by whose power it was produced. This first miracle, though it was not a plague, yet amounted to the threatening of a plague. If it made not Pharaoh feel, it made him fear; and this is God's method of dealing with sinners - he comes upon them gradually. 3. This miracle, though too plain to be denied, is enervated, and the conviction of it taken off, by the magicians' imitation of it, Exo 7:11, Exo 7:12. Moses had been originally instructed in the learning of the Egyptians, and was suspected to have improved himself in magical arts in his long retirement; the magicians are therefore sent for, to vie with him. And some think those of that profession had a particular spite against the Hebrews ever since Joseph put them all to shame, by interpreting a dream which they could make nothing of, in remembrance of which slur put on their predecessors these magicians withstood Moses, as it is explained, Ti2 3:8. Their rods became serpents, real serpents; some think, by the power of God, beyond their intention or expectation, for the hardening of Pharaoh's heart; others think, by the power of evil angels, artfully substituting serpents in the room of the rods, God permitting the delusion to be wrought for wise and holy ends, that those might believe a lie who received not the truth: and herein the Lord was righteous. Yet this might have helped to frighten Pharaoh into a compliance with the demands of Moses, that he might be freed from these dreadful unaccountable phenomena, with which he saw himself on all sides surrounded. But to the seed of the serpent these serpents were no amazement. Note, God suffers the lying spirit to do strange things, that the faith of some may be tried and manifested (Deu 13:3; Co1 11:19), that the infidelity of others may be confirmed, and that he who is filthy may be filthy still, Co2 4:4. 4. Yet, in this contest, Moses plainly gains the victory. The serpent which Aaron's rod was turned into swallowed up the others, which was sufficient to have convinced Pharaoh on which side the right lay. Note, Great is the truth, and will prevail. The cause of God will undoubtedly triumph at last over all competition and contradiction, and will reign alone, Dan 2:44. But Pharaoh was not wrought upon by this. The magicians having produced serpents, he had this to say, that the case between them and Moses was disputable; and the very appearance of an opposition to truth, and the least head made against it, serve those for a justification of their infidelity who are prejudiced against the light and love of it.

Pharaoh - called the wise men - חכמים chacamim, the men of learning. Sorcerers, כשפים cashshephim, those who reveal hidden things; probably from the Arabic root kashafa, to reveal, uncover, etc., signifying diviners, or those who pretended to reveal what was in futurity, to discover things lost, to find hidden treasures, etc. Magicians, חרטמי chartummey, decipherers of abstruse writings. See Clarke's note on Gen 41:8.

They also did in like manner with their enchantments - The word להתים lahatim, comes from להט mor lahat, to burn, to set on fire; and probably signifies such incantations as required lustral fires, sacrifices, fumigations, burning of incense, aromatic and odoriferous drugs, etc., as the means of evoking departed spirits or assistant demons, by whose ministry, it is probable, the magicians in question wrought some of their deceptive miracles: for as the term miracle signifies properly something which exceeds the powers of nature or art to produce, (see Exo 7:9), hence there could be no miracle in this case but those wrought, through the power of God, by the ministry of Moses and Aaron. There can be no doubt that real serpents were produced by the magicians. On this subject there are two opinions:

1.That the serpents were such as they, either by juggling or sleight of hand, had brought to the place, and had secreted till the time of exhibition, as our common conjurers do in the public fairs, etc.

2.That the serpents were brought by the ministry of a familiar spirit, which, by the magic flames already referred to, they had evoked for the purpose.

Both these opinions admit the serpents to be real, and no illusion of the sight, as some have supposed. The first opinion appears to me insufficient to account for the phenomena of the case referred to. If the magicians threw down their rods, and they became serpents after they were thrown down, as the text expressly says, Exo 7:12, juggling or sleight of hand had nothing farther to do in the business, as the rods were then out of their hands. If Aaron's rod swallowed up their rods, their sleight of hand was no longer concerned. A man, by dexterity of hand, may so far impose on his spectators as to appear to eat a rod; but for rods lying on the ground to become serpents, and one of these to devour all the rest so that it alone remained, required something more than juggling. How much more rational at once to allow that these magicians had familiar spirits who could assume all shapes, change the appearances of the subjects on which they operated, or suddenly convey one thing away and substitute another in its place! Nature has no such power, and art no such influence as to produce the effects attributed here and in the succeeding chapters to the Egyptian magicians.

Then Pharaoh also called the wise men and the sorcerers,.... The cunning men and wizards, a sort of jugglers and deceivers, who pretended to great knowledge of things, to discover secrets, tell fortunes, and predict things to come, and by legerdemain tricks, and casting a mist before people's eyes, pretended to do very wonderful and amazing things; and therefore Pharaoh sent for these, to exercise their art and cunning, and see if they could not vie with Moses and Aaron:

now the magicians of Egypt, they also did in like manner with their enchantments; or by their secret wiles and juggles, making things seem to appear to the sight when they did not really, but by dazzling the eyes of men by their wicked and diabolical art, they fancied they saw things which they did not; for the word has the signification of flames of fire, or of a flaming sword, or lance, which being brandished to and fro dazzles the sight. The Targum of Jonathan gives the names of two of these magicians, whom he calls Jannes and Jambres, as does the apostle; see Gill on Ti2 3:8. Josephus (t) calls these magicians of Egypt priests, and Artapanus (u) says, they were priests that lived about Memphis. According to the Arabs (w), the name of the place where they lived was Ausana, a city very ancient and pleasant, called the city of the magicians, which lay to the east of the Nile: their name in the Hebrew language is either from a word which signifies a style, or greying tool, as Fuller (x) thinks, because in their enchantments they used superstitious characters and figures; or, as Saadiah Gaon (y), from two words, the one signifying a "hole", and the other "stopped"; because they bored a hole in a tree to put witchcrafts into it, and stopped it up, and then declared what should be, or they had to say.

Then Pharaoh also called the wise men and the sorcerers, &c.--His object in calling them was to ascertain whether this doing of Aaron's was really a work of divine power or merely a feat of magical art. The magicians of Egypt in modern times have been long celebrated adepts in charming serpents, and particularly by pressing the nape of the neck, they throw them into a kind of catalepsy, which renders them stiff and immovable--thus seeming to change them into a rod. They conceal the serpent about their persons, and by acts of legerdemain produce it from their dress, stiff and straight as a rod. Just the same trick was played off by their ancient predecessors, the most renowned of whom, Jannes and Jambres (Ti2 3:8), were called in on this occasion. They had time after the summons to make suitable preparations--and so it appears they succeeded by their "enchantments" in practising an illusion on the senses.
