7Then the LORD appeared to Abram and said, “I will give this land to your offspring.” So Abram built an altar there to the LORD, who had appeared to him.
8From there Abram moved on to the hill country east of Bethel and pitched his tent, with Bethel to the west and Ai to the east. There he built an altar to the LORD, and he called on the name of the LORD.
— Genesis 12:7-8
