Exodus 6:10-13

King James Version

¹⁰ And the Lord spake unto Moses, saying,

¹¹ Go in, speak unto Pharaoh king of Egypt, that he let the children of Israel go out of his land.

¹² And Moses spake before the Lord, saying, Behold, the children of Israel have not hearkened unto me; how then shall Pharaoh hear me, who am of uncircumcised lips?

¹³ And the Lord spake unto Moses and unto Aaron, and gave them a charge unto the children of Israel, and unto Pharaoh king of Egypt, to bring the children of Israel out of the land of Egypt.
