The children of Reuben, and the children of Gad, and the half-tribe of Manasseh, passed over armed before the children of Israel, as Moses spoke to them:
We may add, that such an immense concourse would have impeded rather than assisted the acquisition of the land of Canaan. All which Moses required, therefore, was simply that the Reubenites and Gadites should not, while their brethren were engaged in carrying on the war, remain indolently at home and eat their food at ease without giving any assistance to those to whom they were indebted for having obtained the inheritance. And the good faith of the forty thousand was approved by their not declining the burdens, toils, and perils of warfare, while the remainder of their own tribes were enjoying quiet. They might readily have alleged that they were as well entitled as the others to exemption, but in proceeding with alacrity after the levy was made, to obey the orders given them, without envying the immunity given to their brethren, they show that they were voluntarily and heartily disposed to do their duty. At the same time, it is not doubtful that by accepting the flower of their tribes, the handle for complaint and quarrel was cut off. For it could not justly have been maintained that not even the aged and worn out, or the young and feeble, were to be spared. Some, perhaps, may be inclined to conjecture that the army was raised not by choice but by lot, though it rather seems to me that all who were most robust and best able to bear fatigue were enrolled.
