של בית נמר – It is the name of a place, as it is written (Numbers 32:36): “Beth-nimrah, [and Beth-haran as fortified towns or as enclosures for flocks].” They tie a rope at the same of the standing corn and continue reaping until the rope runs out and place the Peah the entire rope, and they go back and tie and place the Peah, that is from each and every artisan, that is to say, from each and every row and for this reason they mention these for praise.

An elevated area was secured for them in gehinom. [נתבצר "secured"] is an expression of ערי מבצר ["fortified cities"] (Bamidbar 32:36). That is to say that Hashem arranged an elevated place for them, such that they would not descend too far into gehinom, and thus they did not die.
