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.
