Genesis 46:1-3

So Israel set out with all that he had, and came to Beersheba [where both his father and grandfather had worshiped God], and offered sacrifices to the God of his father Isaac. [Gen 21:33; 26:23-25] And God spoke to Israel in visions of the night and said, “Jacob, Jacob!” And he said, “Here I am.” And He said, “I am God, the God of your father; do not be afraid to go down to Egypt, for I will make you (your descendants) a great nation there.
