Exodus 4:15-17

Wycliffe Bible

¹⁵ Speak thou to him, and put thou my words in his mouth, and I shall be in thy mouth, and in his mouth; and I shall show to you what ye ought to do.

¹⁶ He shall speak for thee to the people, and he shall be thy mouth; forsooth thou shalt be to him in these things, that pertain to God.

¹⁷ Also take thou this rod in thine hand, in which thou shalt do miracles. (And take thou this staff in thy hand, with which thou shalt do miracles.)
