Genesis 13:10-18

10And Lot lifted up his eyes, and beheld all the Plain of Jordan, that it was well watered every where, before the LORD destroyed Sodom and Gomorrah, like the garden of the LORD, like the land of Egypt, as thou goest unto Zoar. 11So Lot chose him all the Plain of Jordan; and Lot journeyed east: and they separated themselves the one from the other. 12Abram dwelled in the land of Canaan, and Lot dwelled in the cities of the Plain, and moved his tent as far as Sodom. 13Now the men of Sodom were wicked and sinners against the LORD exceedingly. 14And the LORD said unto Abram, after that Lot was separated from him, Lift up now thine eyes, and look from the place where thou art, northward and southward and eastward and westward: 15for all the land which thou seest, to thee will I give it, and to thy seed for ever. 16And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered. 17Arise, walk through the land in the length of it and in the breadth of it; for unto thee will I give it. 18And Abram moved his tent, and came and dwelt by the oaks of Mamre, which are in Hebron, and built there an altar unto the LORD.
