The Request of Bnei Gad and Bnei Reuven

The tribe of Reuven and the tribe of Gad had a lot of cattle...And they said:...let this land be given to your servants as an inheritance; don’t make us cross the Yarden (Bamidbar 32). How does the Torah view the request of Bnei Gad and Bnei Reuven to settle on the other side of the Yarden river? The Midrash (Bamidbar Raba 22) teaches the following: ...And similarly you find regarding Bnei Gad and Bnei Reuven that they were rich, and they had a large flock, and they loved their money, and they settled outside of Eretz Yisroel. Therefore, [during the expulsion], out of all the tribes, they were expelled first.
