Joshua 22:24-25

But in fact we have done it for fear, for a reason, saying, ‘In time to come your descendants may speak to our descendants, saying, “What have you to do with the LORD God of Israel? For the LORD has made the Jordan a border between you and us, you children of Reuben and children of Gad. You have no part in the LORD.” So your descendants would make our descendants cease fearing the LORD.’
