Or HaChaim on Deuteronomy 2:15/אור החיים על דברים ב׳:ט״ו

1 וגם יד ה׳ היתה בם, Moreover, the hand of the Lord was against them, etc. Moses meant that not only did the people of that generation suffer death in the desert, but they did not enjoy their sojourn in the desert while it lasted, as we have been told in Bamidbar Rabbah 19,21. The people suffered from a variety of afflictions prior to their deaths. Moses said מקרב המחנה "from the midst of the camp," to indicate that G'd made a clear separation between the people whose death had been decreed and the remainder of the camp. The former were in a constant state of groaning because of their diminution.
