Genesis 13:8-18

So Abram said to Lot, “Please let there be no strife and disagreement between you and me, nor between your herdsmen and my herdsmen, because we are relatives. Is not the entire land before you? Please separate [yourself] from me. If you take the left, then I will go to the right; or if you choose the right, then I will go to the left.” So Lot looked and saw that the valley of the Jordan was well watered everywhere—this was before the LORD destroyed Sodom and Gomorrah; [it was all] like the garden of the LORD, like the land of Egypt, as you go to Zoar [at the south end of the Dead Sea]. Then Lot chose for himself all the valley of the Jordan, and he traveled east. So they separated from each other. Abram settled in the land of Canaan, and Lot settled in the cities of the valley and camped as far as Sodom and lived there. But the men of Sodom were extremely wicked and sinful against the LORD [unashamed in their open sin before Him]. The LORD said to Abram, after Lot had left him, “Now lift up your eyes and look from the place where you are standing, northward and southward and eastward and westward; for all the land which you see I will give to you and to your descendants forever. [Acts 7:5] I will make your descendants [as numerous] as the dust of the earth, so that if a man could count the [grains of] dust of the earth, then your descendants could also be counted. [Gen 28:14] Arise, walk (make a thorough reconnaissance) around in the land, through its length and its width, for I will give it to you.” Then Abram broke camp and moved his tent, and came and settled by the [grove of the great] terebinths (oak trees) of Mamre [the Amorite], which are in Hebron, and there he built an altar to [honor] the LORD.
