Joshua 22:27

27 "So just the opposite is true. The altar will be a witness between us and you. It will be a witness between our children and yours after us. It will also be a witness that we will worship the LORD at his sacred tent. We'll worship him there with our burnt offerings, sacrifices and friendship offerings. Then in days to come your children won't be able to say to ours, 'You don't have anything to do with the Lord.'

Joshua 22:27 Meaning and Commentary

Joshua 22:27

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.

Joshua 22:27 In-Context

25 The LORD has made the Jordan River a border between us and you. You people of Reuben! You people of Gad! You don't have anything to do with the Lord.' If your children say that, they might cause our children to stop worshiping the Lord.

26 "That's why we said to ourselves, 'Let's get ready and build an altar. But let's not build it to offer burnt offerings or sacrifices on it.'

27 "So just the opposite is true. The altar will be a witness between us and you. It will be a witness between our children and yours after us. It will also be a witness that we will worship the LORD at his sacred tent. We'll worship him there with our burnt offerings, sacrifices and friendship offerings. Then in days to come your children won't be able to say to ours, 'You don't have anything to do with the Lord.'

28 "So we said to ourselves, 'Suppose they say that to us sometime. Or suppose they say it to our children after us. Then we'll answer, "Look at this altar. It's exactly like the LORD's altar. Our people built it. They didn't build it to offer burnt offerings and sacrifices on it. Instead, they built it to be a witness between us and you." '

29 "We would never refuse to obey the Lord. We would never turn away from him now. We wouldn't build an altar to offer burnt offerings, grain offerings and sacrifices on it. We wouldn't use any altar other than the altar of the LORD our God. That altar stands in front of his holy tent."
