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."
God Promises Freedom 2
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."
