Numbers 32:5, 19, 32

And they said, If we have found favor in thy sight, let this land be given unto thy servants for a possession; bring us not over the Jordan.

For we will not inherit with them on the other side of the Jordan, and forward; because our inheritance is fallen to us on this side of the Jordan eastward.

We will pass over armed before Jehovah into the land of Canaan, and the possession of our inheritance shall remain with us beyond the Jordan.
