and Aaron spake all the words which Jehovah had spoken unto Moses, and did the signs in the sight of the people.
And he shall be thy spokesman unto the people; and it shall come to pass, that he shall be to thee a mouth, and thou shalt be to him as God.
And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice; for they will say, Jehovah hath not appeared unto thee.
And thou shalt speak unto him, and put the words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.
And Moses came and called for the elders of the people, and set before them all these words which Jehovah commanded him.
