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.
[Patriarchs & 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.
Exodus 7:11 Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. 12 For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods.
May The Lord add His blessing to the study of His word. God bless!
