Genesis 35:5-7

5Then they set out, and the terror of God fell on the towns all around them so that no one pursued them. 6Jacob and all the people with him came to Luz (that is, Bethel) in the land of Canaan.

7There he built an altar, and he called the place El Bethel, El Bethel means God of Bethel. because it was there that God revealed himself to him when he was fleeing from his brother.
