Exodus 7:8 And the Lord spake unto Moses and unto Aaron, saying, 9 When Pharaoh shall speak unto you, saying, Shew a miracle for you: then thou shalt say unto Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent. 10 And Moses and Aaron went in unto Pharaoh, and they did so as the Lord had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent.
[Patriarchs And Prophets pp. 263>264] Again Moses and Aaron entered the lordly halls of the king of Egypt. There, surrounded by lofty columns and glittering adornments, by the rich paintings and sculptured images of heathen gods, before the monarch of the most powerful kingdom then in existence, stood the two representatives of the enslaved race, to repeat the command from God for Israel's release. The king demanded a miracle, in evidence of their divine commission. Moses and Aaron had been directed how to act in case such a demand should be made, and Aaron now took the rod and cast it down before Pharaoh. It became a serpent.
The monarch sent for his “wise men and the sorcerers,” who “cast down every man his rod and they became serpents: but Aaron's rod swallowed up their rods.” Then the king, more determined than before, declared his magicians equal in power with Moses and Aaron; he denounced the servants of the Lord as impostors, and felt himself secure in resisting their demands. Yet while he despised their message, he was restrained by divine power from doing them harm.
It was the hand of God, and no human influence or power possessed by Moses and Aaron, that wrought the miracles which they showed before Pharaoh. Those signs and wonders were designed to convince Pharaoh that the great “I AM” had sent Moses, and that it was the duty of the king to let Israel go, that they might serve the living God. The magicians also showed signs and wonders; for they wrought not by their own skill alone, but by the power of their god, Satan, who assisted them in counterfeiting the work of Jehovah.
The magicians did not really cause their rods to become serpents; but by magic, aided by the great deceiver, they were able to produce this appearance. It was beyond the power of Satan to change the rods to living serpents. The prince of evil, though possessing all the wisdom and might of an angel fallen, has not power to create, or to give life; this is the prerogative of God alone. But all that was in Satan's power to do, he did; he produced a counterfeit. To human sight the rods were changed to serpents. Such they were believed to be by Pharaoh and his court. There was nothing in their appearance to distinguish them from the serpent produced by Moses.
Though the Lord caused the real serpent to swallow up the spurious ones, yet even this was regarded by Pharaoh, not as a work of God's power, but as the result of a kind of magic superior to that of his servants.
Revelation 16:13 And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. 14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
May God add His blessing to the study and practice of His word. "Good night" and God bless!
