1 The LORD said to Moses, “Now you shall see what I will do to Pharaoh, for by a strong hand he will let them go, and by a strong hand he will drive them out of his land.”

2 God spoke to Moses and said to him, “I am the LORD. 3 I appeared to Abraham, Isaac, and Jacob as God Almighty, but by my name LORD I was not known to them. 4 I also established my covenant with them to give them the land of Canaan, the land of their sojourning, where they lived as sojourners. 5 I have also heard the groaning of the Israelites, whom the Egyptians keep in slavery, and I have remembered my covenant. 6 Therefore say to the Israelites, ‘I am the LORD. I will bring you out from under the burdens of the Egyptians, I will rescue you from their slavery, and I will redeem you with an outstretched arm and with great judgments. 7 I will take you as my people, and I will be your God. You shall know that I am the LORD your God, who brings you out from under the burdens of the Egyptians. 8 I will bring you to the land I swore with uplifted hand to give to Abraham, Isaac, and Jacob. I will give it to you as an inheritance. I am the LORD.’ ” 9 Moses spoke this way to the Israelites, but they did not listen to Moses because of anguish of spirit and harsh slavery.

10 The LORD spoke to Moses, saying, 11 “Go in and speak to Pharaoh king of Egypt, so that he may let the Israelites go out of his land.” 12 Moses said before the LORD, “The Israelites have not listened to me. How then will Pharaoh listen to me, when I have uncircumcised lips?”

13 The LORD spoke to Moses and Aaron and gave them a charge concerning the Israelites and Pharaoh king of Egypt, to bring the Israelites out of the land of Egypt.

29 the LORD said to Moses, “I am the LORD. Speak to Pharaoh king of Egypt all that I say to you.” 30 But Moses said before the LORD, “I have uncircumcised lips. How will Pharaoh listen to me?”
