Genesis 12:7-9

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. And Abram journeyed, going on still toward the south.
