Exodus 3:15-16

15God also said to Moses, ‘Say this to the Israelite people: “It is the Lord God who has sent me to you. He is the God that your ancestors worshipped. He is the God of Abraham, Isaac and Jacob.” That is my name for all time. All generations of my people must call me by that name.

16Go and call the leaders of Israel to meet together. Say to them, “The Lord God has appeared to me. He is the God that your ancestors worshipped. He is the God of Abraham, Isaac and Jacob. He said to me, ‘I have been carefully watching my people in Egypt. I have seen the bad things that the Egyptians have done to you.
