Exodus 6:1-6

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] And I have also heard the groaning of the sons of Israel, whom the Egyptians have enslaved, and I have [faithfully] remembered My covenant [with Abraham, Isaac, and Jacob]. Therefore, say to the children of Israel, ‘I am the LORD, and I will bring you out from under the burdens of the Egyptians, and I will free you from their bondage. I will redeem and rescue you with an outstretched (vigorous, powerful) arm and with great acts of judgment [against Egypt].
