Genesis 12:6-8

Abram traveled through that land as far as the great tree of Moreh at Shechem. The Canaanites were living in the land at that time. The LORD appeared to Abram and said, “I will give this land to your descendants.” So Abram built an altar there to the LORD, who had appeared to him. Then he traveled from Shechem to the mountain east of Bethel and set up his tent there. Bethel was to the west, and Ai was to the east. There Abram built another altar to the LORD and worshiped him.
