God also said to Moses, ‘Say this to the Israelites: The Lord, the God of your ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you. This is my name for ever; this is how I am to be remembered in every generation.
Then Jacob said, ‘God of my father Abraham and God of my father Isaac, the Lord who said to me, “Go back to your land and to your family, and I will cause you to prosper,”
The Lord was standing there beside him, saying, ‘I am the Lord, the God of your father Abraham and the God of Isaac. I will give you and your offspring the land on which you are lying.
I will confirm my covenant that is between me and you and your future offspring throughout their generations. It is a permanent covenant to be your God and the God of your offspring after you.
