Exodus 6:1-4

Then the Lord said to Moses, “Now you shall see what I will do to Pharaoh; for under compulsion he will let them go, and under compulsion he will drive them out of his land.”

God spoke further to Moses and said to him, “I am the Lord;

and I appeared to Abraham, Isaac, and Jacob as God Almighty, but by My name, Lord, I did not make Myself known to them.

I also established My covenant with them, to give them the land of Canaan, the land in which they lived as strangers.
