Joshua 22:25-27

25for Jehovah hath made the Jordan a border between us and you, ye children of Reuben and children of Gad; ye have no portion in Jehovah: so might your children make our children cease from fearing Jehovah. 26Therefore we said, Let us now prepare to build us an altar, not for burnt-offering, nor for sacrifice: 27but it shall be a witness between us and you, and between our generations after us, that we may do the service of Jehovah before him with our burnt-offerings, and with our sacrifices, and with our peace-offerings; that your children may not say to our children in time to come, Ye have no portion in Jehovah.
