Exodus 6:2-5
6:2 God spoke to Moses and said to him, “I am the Lord.
6:3 I appeared to Abraham, to Isaac, and to Jacob as God Almighty, but by my name ‘the Lord’ I was not known to them.
6:4 I also established my covenant with them to give them the land of Canaan, where they were living as resident foreigners.
6:5 I have also heard the groaning of the Israelites, whom the Egyptians are enslaving, and I have remembered my covenant.
