Joshua 22:27-28

27Rather, let it be a witness between us and you and the generations to come, that we will worship the LORD in His presence with our burnt offerings, sacrifices, and peace offerings.’ Then in the future, your descendants cannot say to ours, ‘You have no share in the LORD!’

28Therefore we said, ‘If they ever say this to us or to our descendants, we will answer: Look at the replica of the altar of the LORD that our fathers made, not for burnt offerings or sacrifices, but as a witness between us and you.’
