Shemoth (Exodus) 4:10-17

And Mosheh said to יהוה, “O יהוה, I am not a man of words, neither before nor since You have spoken to Your servant, for I am slow of speech and slow of tongue.” And יהוה said to him, “Who has made man’s mouth? Or who makes dumb, or deaf, or seeing, or blind? Is it not I, יהוה? And now, go, and I shall be with your mouth and teach you what to say. But he said, “O יהוה, please send by the hand of him whom You would send.” And the displeasure of יהוה burned against Mosheh, and He said, “Is not Aharon the Lĕwite your brother? I know that he speaks well. And see, he is also coming out to meet you. And when he sees you, he shall be glad in his heart. “And you shall speak to him and put the words in his mouth. And I am with your mouth and with his mouth, and I shall teach you what to do. And he shall speak for you to the people. And it shall be that he shall be a mouth for you, and you shall be an elohim for him. And take this rod in your hand, with which you shall do the signs.
