He was informed that the monarch would not yield until God should visit judgments upon Egypt and bring out Israel by the signal manifestation of His power. Before the infliction of each plague, Moses was to describe its nature and effects, that the king might save himself from it if he chose. Every punishment rejected would be followed by one more severe, until his proud heart would be humbled, and he would acknowledge the Maker of heaven and earth as the true and living God. The Lord would give the Egyptians an opportunity to see how vain was the wisdom of their mighty men, how feeble the power of their gods, when opposed to the commands of Jehovah. He would punish the people of Egypt for their idolatry and silence their boasting of the blessings received from their senseless deities. God would glorify His own name, that other nations might hear of His power and tremble at His mighty acts, and that His people might be led to turn from their idolatry and render Him pure worship.

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.” Exodus 7:11, 12. 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. (PP 263.2) MC VC
