Exodus 6:2-6

2God also told Moses, “I am the LORD. 3I appeared to Abraham, to Isaac, and to Jacob as God Almighty,1 but by My name the LORD I did not make Myself known to them. 4I also established My covenant with them to give them the land of Canaan, the land where they lived as foreigners. 5Furthermore, I have heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered My covenant.

6Therefore tell the Israelites: ‘I am the LORD, and I will bring you out from under the yoke of the Egyptians and deliver you from their bondage. I will redeem you with an outstretched arm and with mighty acts of judgment.
