18 I commanded you at that time, saying, "Yahweh your God has given you this land to possess it: you shall pass over armed before your brothers the children of Israel, all the men of valor.

And I commanded you at that time. This address is directed only to those to whom an inheritance was given on the other side of Jordan; but Moses declares that he had introduced an agreement that the two tribes and a half should not enjoy their possession until they had accommpanied their brethren in the subjugation of the land of Canaan. He says, therefore, that he had given them a place, not where they were at once to settle themselves, but where they might deposit their wives and cattle, until the whole people were peaceably established in their land.
And I commanded (g) you at that time, saying, The LORD your God hath given you this land to possess it: ye shall pass over armed before your brethren the children of Israel, all [that are] meet for the war.
(g) That is, the Reubenites, Gadites, and half Manasseh, as in (Numbers 32:32).
And I commanded you at that time,.... Not all Israel, but the tribes of Reuben and God, and the half tribe of Manasseh; for what follows only concerns them:
saying, the Lord your God hath given you this land to possess it; the land before described, lately in the hands of Sihon and Og; this at their request Moses gave them, by the direction of the Lord, on the following condition:
you shall pass over armed before your brethren the children of Israel, all that are meet for the war; that is, they should pass over Jordan with the rest of the tribes, being armed to assist them in the conquest of Canaan: for this phrase, which we render "before your brethren", does not signify that they went in the forefront of them, only that they were present with them, and joined them in their war against their enemies; see Numbers 32:29 and therefore should be rendered "with your brethren" (a); even as many of them as were able to bear arms, at least as many as Joshua would choose to take of them; for he did not take them all by a great many; see Joshua 4:13.
(a) "cum fratribus vestris", Noldius, p. 531, No. 1492.
You - Namely, the Reubenites and Gadites. All that are meet - In such number as your our brethren shall judge necessary. They were in all above an hundred thousand. Forty thousand of them went over Jordan before their brethren.
