Ex 4:10-17 (King James)

   ¹⁰ And Moses said unto the LORD, O my LORD, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue. ¹¹ And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD? ¹² Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say. ¹³ And he said, O my LORD, send, I pray thee, by the hand of him whom thou wilt send. ¹⁴ And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart. 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.

Ex 4:10-17 (Vulgate)

   ¹⁰ Ait Moyses : Obsecro, Domine, non sum eloquens ab heri et nudiustertius : et ex quo locutus es ad servum tuum, impeditioris et tardioris linguæ sum.
   ¹¹ Dixit Dominus ad eum : Quis fecit os hominis ? aut quis fabricatus est mutum et surdum, videntem et cæcum ? nonne ego ?
   ¹² Perge, igitur, et ego ero in ore tuo : doceboque te quid loquaris.
   ¹³ At ille : Obsecro, inquit, Domine, mitte quem missurus es.
   ¹⁴ Iratus Dominus in Moysen, ait : Aaron frater tuus Levites, scio quod eloquens sit : ecce ipse egreditur in occursum tuum, vidensque te lætabitur corde.
   ¹⁵ Loquere ad eum, et pone verba mea in ore ejus : et ego ero in ore tuo, et in ore illius, et ostendam vobis quid agere debeatis.
   ¹⁶ Ipse loquetur pro te ad populum, et erit os tuum : tu autem eris ei in his quæ ad Deum pertinent.
   ¹⁷ Virgam quoque hanc sume in manu tua, in qua facturus es signa.
