Why did the Jews conquer the land of Og and Sichon? Mentioned in parshas chukas at the end of it.
We see they didn't intend to inherit the land and settle there, since Moshe rabainu was very angry when he heard that the tribes of Reuvain and Gad wanted it. So, without Reuvain and Gad's wanting it, it most likely would have been left desolate, either forever or until some other people took it. Since Moshe didn't want it, why did he go to war with Og and Sichon at all?
- Was it because they are considered among the seven nations which have to be wiped out although they were not living in Israel?
- Or because he couldn't bypass them en route to Israel.
- Or were the people of the land of Canaan paying tribute to Og and Sichon to stop the Jewish people getting to Canaan (as it seems Bolok was doing)?
- Or was Moshe scared they would afterwards join up with kings of the land of Canaan and fight against him so he put them away first?
Does anyone have any documented reason for it?
