“And Moses says to YHWH, “O my Lord, I [am] not a man of words, either yesterday, or before, or since Your speaking to Your servant, for I [am] slow of mouth, and slow of tongue.””— Exodus 4:10 (LSV)
7and He says, “Put your hand back into your bosom”; and he puts his hand back into his bosom, and he brings it out from his bosom, and behold, it has turned back as his flesh—
8“and it has come to pass, if they do not give credence to you, and do not listen to the voice of the first sign, that they have given credence to the voice of the latter sign.
9And it has come to pass, if they do not give credence even to these two signs, nor listen to your voice, that you have taken of the waters of the River, and have poured [it] on the dry land, and the waters which you take from the River have been, indeed, they have become blood on the dry land.”
10And Moses says to YHWH, “O my Lord, I [am] not a man of words, either yesterday, or before, or since Your speaking to Your servant, for I [am] slow of mouth, and slow of tongue.”
11And YHWH says to him, “Who appointed a mouth for man? Or who appoints the mute, or deaf, or open, or blind? Is it not I, YHWH?
12And now, go, and I am with your mouth, and have directed you that which you speak”;
13and he says, “O my Lord, please send by the hand [of another that] You send.”
