Genesis 12:6-8

And Abram passed through the land unto the place of Sichem, unto the plain of Moreh. And the Canaanite was then in the land. And the LORD appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto the LORD, who appeared unto him. And he removed from thence unto a mountain on the east of Beth-el, and pitched his tent, having Beth-el on the west, and Hai on the east: and there he builded an altar unto the LORD, and called upon the name of the LORD.
