Half the tribe of Manasseh and the tribes of Reuben and Gad asked Moses for land on the east side of the Jordan. This land was once the kingdoms of Sihon and Og (Numbers 21:21–35; 32:1–42). In return, they helped the rest of Israel claim their land west of the Jordan (Joshua 1:12–18; 4:12–13). Here, the author confirmed their ownership of these lands.
