Genesis 13:14-18 - The Lord's Third Promise To Abram
14 And Jehovah said unto Abram, after Lot's being parted from him, 'Lift up, I pray thee, thine eyes, and look from the place where thou art, northward, and southward, and eastward, and westward; 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.'
18 And Abram tenteth, and cometh, and dwelleth among the oaks of Mamre, which are in Hebron, and buildeth there an altar to Jehovah.
