Genesis 13:10-18

10Lot 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.) 11So Lot chose for himself the whole plain of the Jordan and set out toward the east. The two men parted company: 12Abram lived in the land of Canaan, while Lot lived among the cities of the plain and pitched his tents near Sodom.

13Now the people of Sodom were wicked and were sinning greatly against the LORD . 14The 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. 15All the land that you see I will give to you and your offspring Or seed; also in verse 16 forever. 16I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted.

17Go, walk through the length and breadth of the land, for I am giving it to you.” 18So 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 .
