Genesis 12:8

From there he moved to the hill country on the east of Bethel and pitched his tent, with Bethel on the west and Ai on the east. And there he built an altar to the LORD and called upon the name of the LORD.

He left from there to go to the mountain on the east of Bethel and pitched his tent, having Bethel on the west, and Ai on the east. There he built an altar to Yahweh and called on Yahweh’s name.
