Exodus 4:15

12 and now, go, and I -- I am with thy mouth, and have directed thee that which thou speakest;`

13 and he saith, `O, my Lord, send, I pray thee, by the hand Thou dost send.`

14 And the anger of Jehovah burneth against Moses, and He saith, `Is not Aaron the Levite thy brother? I have known that he speaketh well, and also, lo, he is coming out to meet thee; when he hath seen thee, then he hath rejoiced in his heart,

15 and thou hast spoken unto him, and hast set the words in his mouth, and I -- I am with thy mouth, and with his mouth, and have directed you that which ye do;

16 and he, he hath spoken for thee unto the people, and it hath come to pass, he -- he is to thee for a mouth, and thou -- thou art to him for God;

17 and this rod thou dost take in thy hand, with which thou doest the signs.`

18 And Moses goeth and turneth back unto Jethro his father-in-law, and saith to him, `Let me go, I pray thee, and I turn back unto my brethren who [are] in Egypt, and I see whether they are yet alive.` And Jethro saith to Moses, `Go in peace.`
