(18, 19) This is a summary of the agreement made and described in Numbers 32:20---32. (See also Note on Joshua 1:12.)

Verses 18-20. - Moses reminds the two and a half tribes of the conditions on which they had received the possessions they had desired beyond Jordan (see Numbers 32:20-32). All that are meet for the war; literally, all the sons of might (בְּנֵי חַיִל), i.e. not all who were men of war or of age to go to war, but men specially powerful and fitted for warlike enterprise. Until the Lord hath given rest auto your brethren (corer. Exodus 33:14).

3:12-20 This country was settled on the Reubenites, Gadites, and half the tribe of Manasseh: see Nu 32. Moses repeats the condition of the grant to which they agreed. When at rest, we should desire to see our brethren at rest too, and should be ready to do what we can towards it; for we are not born for ourselves, but are members one of another.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.
