Exodus 6:2-8

And God said to Moses, “I am Yahweh—‘the LORD.’ I appeared to Abraham, to Isaac, and to Jacob as El-Shaddai—‘God Almighty’—but I did not reveal my name, Yahweh, to them. And I reaffirmed my covenant with them. Under its terms, I promised to give them the land of Canaan, where they were living as foreigners. You can be sure that I have heard the groans of the people of Israel, who are now slaves to the Egyptians. And I am well aware of my covenant with them. “Therefore, say to the people of Israel: ‘I am the LORD. I will free you from your oppression and will rescue you from your slavery in Egypt. I will redeem you with a powerful arm and great acts of judgment. I will claim you as my own people, and I will be your God. Then you will know that I am the LORD your God who has freed you from your oppression in Egypt. I will bring you into the land I swore to give to Abraham, Isaac, and Jacob. I will give it to you as your very own possession. I am the LORD!’”
