Moses thought of the difficulties to be encountered, of the blindness, ignorance, and unbelief of his people, many of whom were almost destitute of a knowledge of God. “Behold,” he said, “when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is His name? what shall I say unto them?” The answer was–“I AM THAT I AM.” “Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.”  

        Moses was commanded first to assemble the elders of Israel, the most noble and righteous among them, who had long grieved because of their bondage, and to declare to them a message from God, with a promise of deliverance. Then he was to go with the elders before the king, and say to him–“The Lord God of the Hebrews hath met with us: and now let us go, we beseech thee, three days’ journey into the wilderness, that we may sacrifice to the Lord our God.”  Moses was forewarned that Pharaoh would resist the appeal to let Israel go. Yet the courage of God’s servant must not fail; for the Lord would make this the occasion to manifest His power before the Egyptians and before His people. “And I will stretch out My hand, and smite Egypt with all My wonders which I will do in the midst thereof: and after that he will let you go.”  

        Direction was also given concerning the provision they were to make for the journey. The Lord declared, “It shall come to pass, that, when ye go, ye shall not go empty: but every woman shall borrow of her neighbor, and of her that sojourneth in her house, jewels of silver, and jewels of gold, and raiment.” The Egyptians had been enriched by the labor unjustly exacted from the Israelites, and as the latter were to start on the journey to their new home, it was right for them to claim the reward of their years of toil. They were to ask for articles of value, such as could be easily transported, and God would give them favor in the sight of the Egyptians. The mighty miracles wrought for their deliverance would strike terror to the oppressors, so that the requests of the bondmen would be granted.  Moses saw before him difficulties that seemed insurmountable. What proof could he give his people that God had indeed sent him? “Behold,” he said, “they will not believe me, nor hearken unto my voice: for they will say, The Lord hath not appeared unto thee.” Evidence that appealed to his own senses was now given. He was told to cast his rod upon the ground. As he did so, “it became a serpent; and Moses fled from before it.” He was commanded to seize it, and in his hand it became a rod. 

        He was bidden to put his hand into his bosom. He obeyed, and “when he took it out, behold, his hand was leprous as snow.” Being told to put it again into his bosom, he found on withdrawing it that it had become like the other. By these signs the Lord assured Moses that His own people, as well as Pharaoh, should be convinced that One mightier than the king of Egypt was manifest among them.  But the servant of God was still overwhelmed by the thought of the strange and wonderful work before him. In his distress and fear he now pleaded as an excuse a lack of ready speech: “O my Lord, I am not eloquent, neither heretofore, nor since Thou hast spoken unto Thy servant; but I am slow of speech, and of a slow tongue.” He had been so long away from the Egyptians that he had not so clear knowledge and ready use of their language as when he was among them.  

        The Lord said unto him, “Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the Lord?” To this was added another assurance of divine aid: “Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.” But Moses still entreated that a more competent person be selected. These excuses at first proceeded from humility and diffidence; but after the Lord had promised to remove all difficulties, and to give him final success, then any further shrinking back and complaining of his unfitness showed distrust of God. It implied a fear that God was unable to qualify him for the great work to which He had called him, or that He had made a mistake in the selection of the man.  Moses was now directed to Aaron, his elder brother, who, having been in daily use of the language of the Egyptians, was able to speak it perfectly. He was told that Aaron was coming to meet him. 

        The next words from the Lord were an unqualified command: “Thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do. And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God. And thou shalt take this rod in thine hand, wherewith thou shalt do signs.” He could make no further resistance, for all ground for excuse was removed. The divine command given to Moses found him self-distrustful, slow of speech, and timid. He was overwhelmed with a sense of his incapacity to be a mouthpiece for God to Israel. But having once accepted the work, he entered upon it with his whole heart, putting all his trust in the Lord. The greatness of his mission called into exercise the best powers of his mind. God blessed his ready obedience, and he became eloquent, hopeful, self-possessed, and well fitted for the greatest work ever given to man. This is an example of what God does to strengthen the character of those who trust Him fully and give themselves unreservedly to His commands.  

        A man will gain power and efficiency as he accepts the responsibilities that God places upon him, and with his whole soul seeks to qualify himself to bear them aright. However humble his position or limited his ability, that man will attain true greatness who, trusting to divine strength, seeks to perform his work with fidelity. Had Moses relied upon his own strength and wisdom, and eagerly accepted the great charge, he would have evinced his entire unfitness for such a work. The fact that a man feels his weakness is at least some evidence that he realizes the magnitude of the work appointed him, and that he will make God his counselor and his strength. Moses returned to his father-in-law and expressed his desire to visit his brethren in Egypt. Jethro’s consent was given, with his blessing, “Go in peace.” With his wife and children, Moses set forth on the journey. He had not dared to make known the object of his mission, lest they should not be allowed to accompany him. Before reaching Egypt, however, he himself thought it best for their own safety to send them back to the home in Midian.  

        A secret dread of Pharaoh and the Egyptians, whose anger had been kindled against him forty years before, had rendered Moses still more reluctant to return to Egypt; but after he had set out to obey the divine command, the Lord revealed to him that his enemies were dead.  On the way from Midian, Moses received a startling and terrible warning of the Lord’s displeasure. An angel appeared to him in a threatening manner, as if he would immediately destroy him. No explanation was given; but Moses remembered that he had disregarded one of God’s requirements; yielding to the persuasion of his wife, he had neglected to perform the rite of circumcision upon their youngest son. He had failed to comply with the condition by which his child could be entitled to the blessings of God’s covenant with Israel; and such a neglect on the part of their chosen leader could not but lessen the force of the divine precepts upon the people. 

        Zipporah, fearing that her husband would be slain, performed the rite herself, and the angel then permitted Moses to pursue his journey. In his mission to Pharaoh, Moses was to be placed in a position of great peril; his life could be preserved only through the protection of holy angels. But while living in neglect of a known duty, he would not be secure; for he could not be shielded by the angels of God. {PP 255.5}
In the time of trouble just before the coming of Christ, the righteous will be preserved through the ministration of heavenly angels; but there will be no security for the transgressor of God’s law. Angels cannot then protect those who are disregarding one of the divine precepts.
