Exodus 6:1-5

Then the LORD told Moses, “Now you will see what I will do to Pharaoh. When he feels the force of my strong hand, he will let the people go. In fact, he will force them to leave his land!” 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.
