And Abraham gave all that he had unto Isaac And Abraham gave all that he had unto Isaac.
Gave unto Isaac ... unto the sons of the concubines. While the chief part of the inheritance went to Isaac, the other sons, Ishmael included, migrating to the "East country" - i:e., Arabia, at first perhaps restricted to the wilderness of Beer-sheba and Paran, but in the widest sense embracing the whole of the two portions of the Arabian peninsula, Arabia Petraea and Deserta-received each a portion of the patrimony, perhaps in cattle and other things. Whether such a distribution was customary (Luke 15:12), or merely a prudential arrangement of Abraham's, the settlement must have given satisfaction, since it is still the rule followed among the pastoral tribes. Some of these sons of Keturah became founders of semi-nomad tribes east and south of Moab; but most of them were insignificant and obscure, or were incorporated by marriage and other bonds of association with the older colonists in the north of the Arabian peninsula, particularly Ishmaelites.
