Exodus 6:7-12

7I will take you as my own people, and I will be your God. Then you will know that I am the LORD your God, who brought you out from under the yoke of the Egyptians.

8And I will bring you to the land I swore with uplifted hand to give to Abraham, to Isaac and to Jacob. I will give it to you as a possession. I am the LORD .’ ”

12But Moses said to the LORD, “If the Israelites will not listen to me, why would Pharaoh listen to me, since I speak with faltering lips Hebrew I am uncircumcised of lips; also in verse 30 ?”
