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 [not only] let them go, but under compulsion he will drive them out of his land.” Then God spoke further to Moses and said to him, “I am the LORD. [Ex 3:14] I appeared to Abraham, to Isaac, and to Jacob (Israel) as God Almighty [El Shaddai], but by My name, LORD, I did not make Myself known to them [in acts and great miracles]. [Gen 17:1] I also established My covenant with them, to give them the land of Canaan, the land in which they lived as strangers (temporary residents, foreigners). [Gen 12:1-3; 13:14-17; 15:18-21; 17:19; 26:3, 4; 28:13]
