Genesis 13 (NKJV)
14 And the Lord said to Abram, after Lot had separated from him: “Lift your eyes now and look from the place where you are–northward, southward, eastward, and westward;
15 for all the land which you see I give to you and your descendants forever.
16 And I will make your descendants as the dust of the earth; so that if a man could number the dust of the earth, then your descendants also could be numbered.
17 Arise, walk in the land through its length and its width, for I give it to you.”
