An altar, not for burnt-offering, nor for sacrifice - Because this would have been in flat opposition to the law, Lev 17:8, Lev 17:9; Deu 12:4-6, Deu 12:10, Deu 12:11, Deu 12:13, Deu 12:14, which most positively forbade any sacrifice or offering to be made in any other place than that one which the Lord should choose. Therefore the altar built by the Reubenites, etc., was for no religious purpose, but merely to serve as a testimony that they were one people with those on the west of Jordan, having the same religious and civil constitution, and bound by the same interests to keep that constitution inviolate.

But that it may be a witness between us and you, and our generations after us,.... That we are one people, worship one God, and serve at one altar, of which this built was a resemblance, and would put them in mind of it:

that we might do the service of the Lord before him; in the tabernacle, and at the altar, in the place where he had chosen to put his name and dwell:

with our burnt offerings, and with our sacrifices, and with our peace offerings; to be brought at stated times, or as occasion required:

that your children may not say to our children, in time to come, ye have no part in the Lord; nor right to his altar, and so forbid them offering their sacrifices on it; or"have no part in the Word of the Lord,''as the Targum; the Messiah, whose sacrifice was typified by the sacrifices of the legal dispensation, and all such, who offered theirs in the faith of that, had a part in it, and their sins were expiated by it.

Then the children of Reuben . . . answered--repudiating, in the strongest terms, the alleged crime, and deponing that so far from entertaining the intention imputed to them, their only object was to perpetuate the memory of their alliance with Israel [Jos 22:24-25], and their adherence to the worship of Israel's God [Jos 22:26-27].
