And as a sign that it should be so, He said that after Moses had brought his people out of Egypt, they should serve God in this mountain.
But Moses had many fears. He knew that he had been brought up as an Egyptian, and he feared that his people would not listen to his words.
Then the Lord showed signs to Moses to help his faith.
He turned the rod in Moses' hand into a serpent, and then when he was afraid of it, the Lord told him to take it in his hand and it became a rod again.
He also turned his hand white with leprosy, and then changed it again to natural flesh, and told Moses, that these, and other signs he should show in Egypt—to prove that he was sent of God.
But Moses felt himself to be so weak and faithless as a leader of his people, that he still cried out that he was "slow of speech, and of a slow tongue," and when the Lord said, "I will teach thee what thou shalt say," he did not believe, but begged the Lord to send by whom he would, only not by him.
Then the Lord said that Aaron, the brother of Moses could speak well, and that he should go with him to Pharoah and to his people, and should speak for him, but that the wisdom and power of God should be with Moses, and that he should do wonders with the rod in his hand.
