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.Until the Lord have given rest unto your brethren, as well as unto you,.... Rest from their enemies, and habitations to dwell quietly in; so the land of Canaan is called a rest, Deuteronomy 12:9 typical of the rest which remains for the people of God:

and until they also possess the land which the Lord your God hath given them beyond Jordan; for so Canaan was with respect to Moses and the people with him, who were then in the plains of Moab; otherwise the country in which he was with respect to Canaan is usually called beyond Jordan; this the Lord had given in promise to Israel, and they were just now ready to enter into and possess it, by virtue of his gift, and which made it sure unto them:

and then shall ye return every man unto his possession, which I have given you; as accordingly they did, Joshua 22:1.
