Genesis 13:15-17

Young's Literal Translation

¹⁵ for the whole of the land which thou are seeing, to thee I give it, and to thy seed -- to the age.

¹⁶ And I have set thy seed as dust of the earth, so that, if one is able to number the dust of the earth, even thy seed is numbered;

¹⁷ rise, go up and down through the land, to its length, and to its breadth, for to thee I give it.'
