Genesis 12:6-9

6Abram passed through the land as far as the site of Shechem, to the [great] terebinth (oak) tree of Moreh. Now the Canaanites were in the land at that time.

7Then the Lord appeared to Abram and said, “I will give this land to your descendants.” So Abram built an altar there to [honor] the Lord who had appeared to him.

8Then he moved on from there to the mountain on the east of Bethel, and pitched his tent, with Bethel on the west and Ai on the east; and there he built an altar to the Lord and called on the name of the Lord [in worship through prayer, praise, and thanksgiving].

9Then Abram journeyed on, continuing toward the Negev (the South country of Judah).
