God said to Moses, "Now you'll see what I'll do to Pharaoh: With a strong hand he'll send them out free; with a strong hand he'll drive them out of his land."
God continued speaking to Moses, reassuring him, "I am God.
I appeared to Abraham, Isaac, and Jacob as The Strong God, but by my name God (I-Am-Present) I was not known to them.
I also established my covenant with them to give them the land of Canaan, the country in which they lived as sojourners.
But now I've heard the groanings of the Israelites whom the Egyptians continue to enslave and I've remembered my covenant.
Therefore tell the Israelites:
I'll take you as my own people and I'll be God to you. You'll know that I am God, your God who brings you out from under the cruel hard labor of Egypt.
