But the Lord replied to Moses, "Now you are going to see what I will do to Pharaoh: he will let them go because of My strong hand; he will drive them out of his land because of My strong hand."
Then God spoke to Moses, telling him, "I am Yahweh.
I appeared to Abraham, Isaac, and Jacob as God Almighty, but I did not make My name Yahweh known to them.
I also established My covenant with them to give them the land of Canaan, the land they lived in as foreigners.
Furthermore, I have heard the groaning of the Israelites, whom the Egyptians are forcing to work as slaves, and I have remembered My covenant.
"Therefore tell the Israelites: I am Yahweh, and I will deliver you from the forced labor of the Egyptians and free you from slavery to them. I will redeem you with an outstretched arm and great acts of judgment.
I will take you as My people, and I will be your God. You will know that I am Yahweh your God, who delivered you from the forced labor of the Egyptians.
I will bring you to the land that I swore to give to Abraham, Isaac, and Jacob, and I will give it to you as a possession. I am the Lord."
Moses told this to the Israelites, but they did not listen to him because of their broken spirit and hard labor.
Then the Lord spoke to Moses,
"Go and tell Pharaoh king of Egypt to let the Israelites go from his land."
But Moses said in the Lord's presence: "If the Israelites will not listen to me, then how will Pharaoh listen to me, since I am such a poor speaker?"
Then the Lord spoke to Moses and Aaron and gave them commands concerning both the Israelites and Pharaoh king of Egypt to bring the Israelites out of the land of Egypt.

On the day the Lord spoke to Moses in the land of Egypt,
He said to him, "I am the Lord; tell Pharaoh king of Egypt everything I am telling you."
But Moses replied in the Lord's presence, "Since I am such a poor speaker, how will Pharaoh listen to me?"
