Exodus 6:2-5

2God spoke further to Moses and said to him, “I am 1the Lord;

3and I appeared to Abraham, Isaac, and Jacob, as 23God Almighty, but by 4My name, 5Lord, I did not make Myself known to them.

4I also established 6My covenant with them, to give them the land of Canaan, the 7land in which they sojourned.

5Furthermore I have 8heard the groaning of the sons of Israel, because the Egyptians are holding them in bondage, and I have remembered My covenant.
