Angels instructed Moses that God had chosen him to deliver the children of Israel. The rulers among the children of Israel were also taught by angels that the time for their deliverance was nigh, and that Moses was the man whom God would use to accomplish this work. Moses thought that the children of Israel would be delivered by warfare, and that he would stand at the head of the Hebrew host, to conduct the warfare against the Egyptian armies and deliver his brethren from the yoke of oppression. Having this in view, Moses guarded his affections, that they might not be strongly placed upon his adopted mother or upon Pharaoh, lest it should be more difficult for him to remain free to do the will of God.

The Lord preserved Moses from being injured by the corrupting influences around him. The principles of truth, received in his youth from God-fearing parents, were never forgotten by him. And when he most needed to be shielded from the corrupting influences attending a life at court, then the lessons of his youth bore fruit. The fear of God was before him. And so strong was his love for his brethren, and so great was his respect for the Hebrew faith, that he would not conceal his parentage for the honor of being an heir of the royal family. SR 109.1
When Moses was forty years old, “he went out unto his brethren, and looked on their burdens; and he spied an Egyptian smiting an Hebrew, one of his brethren. And he looked this way and that way, and when he saw that there was no man, he slew the Egyptian, and hid him in the sand. And when he went out the second day, behold, two men of the Hebrews strove together: and he said to him that did the wrong, Wherefore smitest thou thy fellow? And he said, Who made thee a prince and a judge over us? intendest thou to kill me, as thou killedst the Egyptian? And Moses feared, and said, Surely this thing is known. Now when Pharaoh heard this thing he sought to slay Moses. But Moses fled from the face of Pharaoh, and dwelt in the land of Midian.” The Lord directed his course, and he found a home with Jethro, a man that worshiped God. He was a shepherd, also priest of Midian. His daughters tended his flocks. But Jethro's flocks were soon placed under the care of Moses, who married Jethro's daughter and remained in Midian forty years. SR 109.2
Moses was too fast in slaying the Egyptian. He supposed that the people of Israel understood that God's special providence had raised him up to deliver them. But God did not design to deliver the children of Israel by warfare, as Moses thought, but by His own mighty power, that the glory might be ascribed to Him alone. God overruled the act of Moses in slaying the Egyptian to bring about His purpose. He had in His providence brought Moses into the royal family of Egypt, where he had received a thorough education; and yet he was not prepared for God to entrust to him the great work He had raised him up to accomplish. Moses could not immediately leave the king's court and the indulgences granted him as the king's grandson to perform the special work of God. He must have time to obtain an experience and be educated in the school of adversity and poverty. While he was living in retirement, the Lord sent His angels to especially instruct him in regard to the future. Here he learned more fully the great lesson of self-control and humility. He kept the flocks of Jethro, and while he was performing his humble duties as a shepherd, God was preparing him to become a spiritual shepherd of His sheep, even of His people Israel. SR 110.1
As Moses led the flock to the desert and came to the mountain of God, even to Horeb, “the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush.” “And the Lord said, I have surely seen the affliction of My people which are in Egypt, and have heard their cry by reason of their taskmasters; for I know their sorrows; and I am come down to deliver them out of the hand of the Egyptians, and to bring them up out of that land unto a good land and a large, unto a land flowing with milk and honey.... Now therefore, behold, the cry of the children of Israel is come up unto Me: and I have also seen the oppression wherewith the Egyptians oppress them. Come now therefore, and I will send thee unto Pharaoh, that thou mayest bring forth My people the children of Israel out of Egypt.” SR 110.2
The time had fully come when God would have Moses exchange the shepherd's staff for the rod of God, which He would make powerful in accomplishing signs and wonders, in delivering His people from oppression, and in preserving them when pursued by their enemies. SR 111.1
Moses consented to perform the mission. He first visited his father-in-law and obtained his consent for himself and his family to return into Egypt. He did not dare to tell Jethro his message to Pharaoh, lest he should be unwilling to let his wife and children accompany him on such a dangerous mission. The Lord strengthened him and removed his fears by saying to him, “Return into Egypt: for all the men are dead which sought thy life.” SR 111.2
