Exodus 6:1-4

6:1 Then the Lord said to Moses, “Now you will see what I will do to Pharaoh, for compelled by my strong hand he will release them, and by my strong hand he will drive them out of his land.”

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.
