Genesis 12:6-10

Abram passed through the land as far as the site of Shechem, to the oak of Moreh. Now the Canaanites were in the land at that time.

And the Lord appeared to Abram and said, “To your descendants I will give this land.” So he built an altar there to the Lord who had appeared to him.

Then he proceeded 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 upon the name of the Lord.

Then Abram journeyed on, continuing toward the Negev.

Now there was a famine in the land; so Abram went down to Egypt to live there for a time, because the famine was severe in the land.
