Genesis 13:14-16

14 The  Lord said to Abram, after Lot had separated from him, “Lift up your eyes and look from the place where you are, a northward and southward and eastward and westward, 15 for all the land that you see I will give b to you and c to your offspring forever. 16  d I will make your offspring as the dust of the earth, so that if one can count the dust of the earth, your offspring also can be counted.
