Genesis 12:6-8

Abram traveled through the land as far as the site of the great tree of Moreh at Shechem. At that time the Canaanites were in the land. The LORD appeared to Abram and said, “To your offspring I will give this land.” So he built an altar there to the LORD, who had appeared to him. From there he went on toward the hills east of Bethel and pitched his tent, with Bethel on the west and Ai on the east. There he built an altar to the LORD and called on the name of the LORD.
