Genesis 12:6-8

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