Genesis 12:6-9

6And Abram passed through the land unto the place of Sichem, unto the plain of Moreh. And the Canaanite was then in the land.1 7And Yhwh appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto Yhwh, who appeared unto him. 8And he removed from thence unto a 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 Yhwh, and called upon the name of Yhwh. 9And Abram journeyed, going on still toward the south.2
