Genesis 13:7-18

And quarreling arose between Abram’s herders and Lot’s. The Canaanites and Perizzites were also living in the land at that time. So Abram said to Lot, “Let’s not have any quarreling between you and me, or between your herders and mine, for we are close relatives. Is not the whole land before you? Let’s part company. If you go to the left, I’ll go to the right; if you go to the right, I’ll go to the left.” Lot looked around and saw that the whole plain of the Jordan toward Zoar was well watered, like the garden of the LORD, like the land of Egypt. (This was before the LORD destroyed Sodom and Gomorrah.) So Lot chose for himself the whole plain of the Jordan and set out toward the east. The two men parted company: Abram lived in the land of Canaan, while Lot lived among the cities of the plain and pitched his tents near Sodom. Now the people of Sodom were wicked and were sinning greatly against the LORD. The LORD said to Abram after Lot had parted from him, “Look around from where you are, to the north and south, to the east and west. All the land that you see I will give to you and your offspring forever. I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted. Go, walk through the length and breadth of the land, for I am giving it to you.” So Abram went to live near the great trees of Mamre at Hebron, where he pitched his tents. There he built an altar to the LORD.
