Parallel
Exodus 6:12
Brenton's English Septuagint · Berean Standard Bible
And Moses spoke before the Lord, saying, Behold, the children of Israel hearkened not to me, and how shall Pharao hearken to me? and I am not eloquent.
But in the LORD’s presence Moses replied, “If the Israelites will not listen to me, then why would Pharaoh listen to me, since I am unskilled in speech (note: Hebrew I have uncircumcised lips; also in verse 30)?”
