Genesis 13:14-18

After Lot had gone, the LORD said to Abram, “Look as far as you can see in every direction—north and south, east and west. I am giving all this land, as far as you can see, to you and your descendants as a permanent possession. And I will give you so many descendants that, like the dust of the earth, they cannot be counted! Go and walk through the land in every direction, for I am giving it to you.” So Abram moved his camp to Hebron and settled near the oak grove belonging to Mamre. There he built another altar to the LORD.
