Joshua 22:24-25

But truly we have done this out of concern, for a reason, saying, ‘In time to come your sons may say to our sons, “What have you to do with the LORD, the God of Israel? For the LORD has made the Jordan a border between us and you, you sons of Reuben and sons of Gad; you have no portion in the LORD.” So your sons may make our sons stop fearing the LORD.’
