And Aaron spoke all the words which the Lord had spoken to Moses, and did the signs in the sight of the people.
So Moses came and called the elders of the people, and set before them all these words which the Lord had commanded him.
Then Moses answered, “But behold, they will not believe me or listen to my voice, for they will say, ‘The Lord did not appear to you.’ ”
And you shall speak to him and put the words in his mouth; and I will be with your mouth and with his mouth, and will teach you what you shall do.
He shall speak for you to the people; and he shall be a mouth for you, and you shall be to him as God.
