Numbers 32:6

Moses assumed that Reuben and Gad wanted to stay east of the Jordan River to avoid the dangers that awaited the other tribes in Canaan (compare chapters 13–14).

Moses said unto the children of Gad and to the children of Reuben, Shall your brethren go to war, and shall ye sit here--Their language was ambiguous; and Moses, suspicious that this proposal was an act of unbelief, a scheme of self-policy and indolence to escape the perils of warfare and live in ease and safety, addressed to them a reproachful and passionate remonstrance. Whether they had really meditated such a withdrawal from all share in the war of invasion, or the effect of their leader's expostulation was to drive them from their original purpose, they now, in answer to his impressive appeal, declared it to be their sincere intention to co-operate with their brethren; but, if so, they ought to have been more explicit at first.

And Moses said unto the children of Gad. So sharp and severe a reproof shews us the greatness of the wrong: for neither did inconsiderate warmth carry away Moses into such violent anger, nor did he fall into error, so as to deliver his opinion on a point which he did not well understand. He knew, therefore, what the sons of Gad and Reuben asked; and hence he inveighed against them thus vehemently, because they desired to lacerate the body of the Church by this wicked severance. He begins by expostulating with them with regard to their sinful and unreasonable covetousness, in that they sought to indulge in idleness, when their brethren were about to march through a hostile land; for they were possessed of no rightful superiority, so as to throw upon the others all the labors, perils, and burdens of the war. Since, therefore, God had imposed the same condition upon all, [213] it was not right that part of them should be exempted from it, as if by privilege. More severely, however, is their ingratitude and perverseness towards God chastised, than their injustice towards their brethren, whilst he alleges to their reproach, that thus the hearts of the children of Israel would be broken, [214] so that they wouht refuse to obey the call of God.

And Moses said unto the children of Gad, and to the children of Reuben,.... Being displeased with their motion, as his following discourse shows, it having at first sight an appearance of covetousness and cowardice:

shall your brethren go to war, and shall ye sit here? it is not reasonable that your brethren should be left by you and engage in a war with your common enemies, to dispossess them of their land before they can settle in it and you remain here easy and quiet in the possession of a fruitful country.

In case and peace, whilst your brethren are engaged in a bloody war. Their words were ambiguous, and Moses thought this to be an act of unbelief and sloth and self-love and policy.

Moses first of all blames their want of brotherly feeling: "Shall your brethren go into the war, and ye sit here?" He then calls their attention to the fact, that by their disinclination they would take away the courage and inclination of the other tribes to cross over the Jordan and conquer the land, and would bring the wrath of God upon Israel even more than their fathers who were sent from Kadesh to spy out the land, and who led away the heart of the people into rebellion through their unfavourable account of the inhabitants of Canaan, and brought so severe a judgment upon the congregation. מן את־לב הניא, to hold away the heart, i.e., render a person averse to anything. The Keri תּניאוּן, as in Num 32:9, is unquestionably to be preferred to the Kal תּנוּאוּן, in the Kethib of Num 32:7. - In Num 32:8-13, Moses reminds them of the occurrences described in ch. 13 and 14. On the expression, "wholly followed Jehovah," cf. Num 14:24. The words, "He drove them about in the desert," caused them to wander backwards and forwards in it for forty years, point back to Num 14:33-35.
