Joshua 22:25-27

25For the Lord has made the Jordan a border between us and you descendants of Reuben and Gad. You have no share in the Lord! ’ So your descendants may cause our descendants to stop fearing the Lord.

26“Therefore we said: Let’s take action and build an altar for ourselves, but not for burnt offering or sacrifice.

27Instead, it is to be a witness between us and you, and between the generations after us, so that we may carry out the worship of the Lord in his presence with our burnt offerings, sacrifices, and fellowship offerings. Then in the future, your descendants will not be able to say to our descendants, ‘You have no share in the Lord!’
