Genesis 13:12-18

So Abram settled in the land of Canaan, and Lot moved his tents to a place near Sodom and settled among the cities of the plain. But the people of this area were extremely wicked and constantly sinned against the LORD. 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.
