Genesis 13:14-18

14The 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;

15for all the land which you see I will give to you and to your descendants forever.

16I 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.

17Arise, walk (make a thorough reconnaissance) around in the land, through its length and its width, for I will give it to you.”

18Then 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.
