Joshua 22:27-29

To build another altar for offering sacrifices would be the same as turning our backs on the LORD and rebelling against him. We could never do that! No, we built the altar to remind us and you and the generations to come that we will worship the LORD. And so we will keep bringing our sacrifices to the LORD's altar, there in front of his sacred tent. Now your descendants will never be able to say to our descendants, “You can't worship the LORD.” But if they do say this, our descendants can answer back, “Look at this altar our ancestors built! It's like the LORD's altar, but it isn't for offering sacrifices. It's here to remind us and you that we belong to the LORD, just as much as you do.”
