Joshua 22:25-27

25For the Lord has made the Jordan a boundary between us and you, you people of Reuben and people of Gad. You have no portion in the Lord.' So your children might make our children cease to worship the Lord.

26Therefore we said, 'Let us now build an altar, not for burnt offering, nor for sacrifice,

27but to be a witness between us and you, and between our generations after us, that we do perform the service of the Lord in his presence with our burnt offerings and sacrifices and peace offerings, so your children will not say to our children in time to come, "You have no portion in the Lord."'
