Exodus 6:12

9 Moses spoke so to the children of Israel, but they didn`t listen to Moses for anguish of spirit, and for cruel bondage.

10 Yahweh spoke to Moses, saying,

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

12 Moses spoke before Yahweh, saying, "Behold, the children of Israel haven`t listened to me. How then shall Pharaoh listen to me, who am of uncircumcised lips?"

13 Yahweh spoke to Moses and to Aaron, and gave them a charge to the children of Israel, and to Pharaoh king of Egypt, to bring the children of Israel out of the land of Egypt.
