(1.) Reuben basely declined the service, v. 15, 16. Justly had he long ago been deprived of the privileges of the birth-right, and still does his dying father's doom stick by him: unstable as water, he shall not excel. Two things hindered them from engaging:—[1.] Their divisions. This jarring string she twice strikes upon to their shame: For the divisions of Reuben (or in these divisions) there were great thoughts, impressions, and searchings of heart. Not only for their division from Canaan by the river Jordan, which needed not to have hindered them had they been hearty in the cause, for Gilead abode beyond Jordan, and yet from Machir of Gilead came down governors; but it means either that they were divided among themselves, could not agree who should go or who should lead, each striving to gain the posts of honour and shun those of danger, some unhappy contests in their tribe kept them from uniting together, and with their brethren, for the common good, or that they were divided in their opinion of this war from the rest of the tribes, thought the attempt either not justifiable or not practicable, and therefore blamed those that engaged in it and did themselves decline it. This occasioned great searchings of heart among the rest, especially when they had reason to suspect that, whatever Reuben pretended, his sitting still now proceeded from a cooling of his affections to his brethren and an alienation of mind from them, which occasioned them many sad thoughts. It grieves us to see our mother's children angry with us for doing our duty and looking strange upon us when we most need their friendship and assistance. [2.] Their business in the world: Reuben abode among the sheepfolds, a warmer and safer place than the camp, pretending they could not conveniently leave the sheep they tended; he loved to hear the bleatings of the flocks, or, as some read it, the whistlings of the flocks, the music which the shepherds made with their oaten reeds or pipes, and the pastorals which they sung; these Reuben preferred before the martial drum and trumpet. Thus many are kept from doing their duty by the fear of trouble, the love of ease, and an inordinate affection to their worldly business and advantage. Narrow selfish spirits care not what becomes of the interests of God's church, so they can but get, keep, and save money. All seek their own, Phil. ii. 21.
