Exodus 4:15-17

King James Version

¹⁵ And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.

¹⁶ And he shall be thy spokesman unto the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God.

¹⁷ And thou shalt take this rod in thine hand, wherewith thou shalt do signs.
