Numbers 32:2

2.The children of Gad and the children of Reuben came. Their request was apparently a reasonable one, that, since God had driven out the inhabitants of the land, and its fertility invited them to dwell there, the possession of these empty and deserted fields should not be denied them. Their modesty also was praiseworthy, in that they neither detach themselves from the people, nor seditiously and violently seize upon the places which were so suitable for them; but seek to obtain them by the permission of Moses and the elders, as if they submitted their cause to their decision. But as I have just said, their private interest had so laid hold of their minds, that the main point did not occur to them, viz., that the land of Canaan was set before them all, in order that they might dwell together there separate from heathen nations; and, again, that it was unjust for them not only to enjoy repose, whilst the others were fighting, but also to be settled in an assured and peaceable habitation, while the ten tribes were still advancing to the conquest of the promised land.
