By lot [was] their inheritance
Every tribe had its part and portion assigned to it, by the casting of lots; which was done to prevent any future quarrels, animosities and strifes among the tribes, the disposition being of the Lord; and to show the exact agreement between the lot and the divine predictions by Jacob and Moses; and to make it appear that the division of the land was not owing to the private combination of the above men, and their private settlement of it; but to the providence of God, the directors of the lot; their chief business was to see that the lot was executed in a faithful manner, and that every tribe had its allotment according to it. In this Canaan was a type of the heavenly inheritance, which the saints obtain by lot, in and through Christ, the antitypical Joshua, ( Ephesians 1:11 ) ;
for the nine tribes, and [for] the half tribe;
see ( Joshua 13:7 ) ; the reason why this number of them is particularly mentioned follows.
