Joshua 22:27-28

27but to be a witness between us and you, and between our generations after us, that we might do service to 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 future, Ye have no portion in Jehovah.

28And we said, If it shall be that in future they so say to us and to our generations, we will say, Behold the pattern of the altar of Jehovah which our fathers made, not for burnt-offering, nor for sacrifice, but as a witness between us and you.
