And Moses said before the Lord, Behold, I am not able in speech, and how shall Pharao hearken to me?

And Moses said before the Lord, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken unto me?

Moses said before Yahweh, “Behold, I am of uncircumcised lips, and how shall Pharaoh listen to me?”
