Verses 14-18:
Following the departure of Lot, Jehovah spoke to Abram, to reaffirm the land-grant portion of His covenant, and to comfort him in the sorrow caused by Lot’s leaving. On the mountain peaks between Bethel and Hai (Ai) one has a commanding view of almost the entire Land. To the north lie the hills dividing Judaea from the rich plains of Samaria. To the south one may see as far as the Hebron range of hills. To the east are visible the mountains of Moab and the fertile crescent to which Lot had departed. To the west lies the Mediterranean sea-coast, with its prospects of foreign commerce. As far as the eye could see, all this territory is included in the Divine land-grant.
There is no conflict between this promise, and Stephen’s statement of Ac 7:5 (q.v.). Abram lived out his life as a nomadic chieftain, in peace among the inhabitants of the Land. The only part of this territory he could claim as his own was the burial-plot he purchased for his beloved wife, Ge 28:17-20. But Abram’s descendants did occupy this territory under Joshua. The full realization of the entire land-grant is yet to come, however, and will be realized during the coming reign of the Messiah, Lu 1:32, 33.
The promise of a "seed" is renewed. This promise relates to the earthly or physical seed, in the figure of the "dust."
Some time after this, Abram moved from the hills of Bethel to the plain, elon (terebinth or oak), of Mamre - an Amorite chieftain who became a friend and ally of Abram.
Hebron lies twenty-two miles south of Jerusalem on the road to Beersheba. It is an ancient town, pre-dating even Zoan of Egypt (Nu 13:22). It is also known as Kirjath-arba (Ge 22:3; 25:7; Jos 14:15), or the "city of Arba," likely because it became the dwelling of Arba the Anakite.
