The Lord directed Moses to say unto Pharaoh, “Thus saith the Lord, Israel is my son, even my first-born. And I say unto thee, Let my son go, that he may serve me. And if thou refuse to let him go, behold, I will slay thy son, even thy first-born.” The Lord called Israel his first-born, because he had singled them out from all people to be the depositaries of his law, the obedience of which would preserve them pure amidst idolatrous nations. He conferred upon them special privileges, such as were generally conferred upon the first-born son. (3SG 195.1) MC VC

As Moses journeyed to Egypt, the angel of the Lord met him and assumed a threatening posture, as though he would slay him. He was fearful of his life. He had yielded to the refusal of his wife to have their son circumcised, and, in compliance with her wishes, had neglected to obey God. His wife, fearful that her husband might be slain, overcame her feelings of undue affection for her son, and performed the act herself. After this, the angel let Moses go. In his mission to Pharaoh, he was to be placed in a perilous position, where his life would be exposed to the will of the king, if God did not by his power, through the presence of his angels, preserve him. While Moses was living in neglect of one of God’s positive commands, his life would not be secure, for God’s angels could not protect him while in disobedience. Therefore, the angel met him in the way and threatened his life. He did not explain to Moses why he assumed that threatening aspect. Moses knew that there was a cause. He was going to Egypt according to God’s express command, therefore the journey was right. He at once remembered that he had not obeyed God in performing the ordinance of circumcision upon his youngest son, and had yielded to his wife’s entreaties to postpone the ceremony. After he had obeyed the command of God he was free to go before Pharaoh, and there was nothing in the way to hinder the ministration of angels in connection with his work. (3SG 195.2) MC VC

In the time of trouble, just previous to the coming of Christ, the lives of the righteous will be preserved through the ministration of holy angels. Those who come up to that trying time, neglecting to obey God’s commands, will have no security of their lives. Angels cannot protect them from the wrath of their enemies while they are living in neglect of any known duty, or express command of Jehovah. (3SG 196.1) MC VC

The Lord had informed Moses that Aaron, his brother, three years older than himself, would come forth to meet him, and when he should see him, would be glad. They had been separated for many years. Angels of God had instructed Moses in regard to the work he should perform. Angels also were sent to teach Aaron to go forth and meet Moses, for the Lord had chosen him to be with Moses, and when he should meet his brother to listen to his words, for God had given Moses words to speak to him in regard to the part he should act in connection with the deliverance of Israel. “And the Lord said to Aaron, Go into the wilderness to meet Moses. And he went, and met him in the mount of God, and kissed him. And Moses told Aaron all the words of the Lord who had sent him, and all the signs which he had commanded him. And Moses and Aaron went and gathered together all the elders of the children of Israel. And Aaron spake all the words which the Lord had spoken unto Moses, and did the signs in the sight of the people. And the people believed. And when they heard that the Lord had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshiped.” (3SG 196.2) MC VC
