Exodus 6:1-5

Then the LORD said to Moses, ‘Now you will see what I will do to Pharaoh: because of my mighty hand he will let them go; because of my mighty hand he will drive them out of his country.’ God also said to Moses, ‘I am the LORD. I appeared to Abraham, to Isaac and to Jacob as God Almighty, but by my name the LORD I did not make myself known to them. I also established my covenant with them to give them the land of Canaan, where they resided as foreigners. Moreover, I have heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant.
