This proposal was very equitable, and it was honestly made and
   faithfully executed; though it did not imply that all men
   capable of bearing arms should go, and so leave their families
   and possessions defenceless, but only a sufficient detachment
   of them.  Among the inhabitants of the land were the
   Ammonites, Moabites, Idumeans, and the remains of the
   Midianites and Amorites; and as it was impossible for the
   women and children to keep the defenced cities, when placed in
   them, many of the men of war must of course stay behind.  In
   the last census (ch. 26), the tribe of Reuben consisted of
   43,730; men; the tribe of Gad 40,500; and the tribe of Manasseh
   52,700; the half of which is 26,350; which together amount to
   110,580.  Now from Jos 4:13, we learn, that of these tribes
   only 40,000; armed men passed over Jordan to assist their
   brethren:  consequently 70,580; men were left behind for the
   defence of the women, the children, and the flocks:  which was
   amply sufficient for this purpose.
