על צבאתם — This is the same as בצבאותם with their hosts — all their hosts according to their tribes. Sometimes the word על is merely used in place of a single letter (ב as a prefix); e. g., (Genesis 27:40) “על חרבך shalt thou live” which is the same as בחרבך, by thy sword; (Ezekiel 33:26) “Ye stand על חרבכם” which is the same as בחרבכם, by your sword.

ועל חרבך—The phrase is equivalent to בחרבך BY THY SWORD. The word על is sometimes used instead of the prefix ב, as (Ezekiel 33:26) “Ye stand by your sword (על חרבכם)”, which is the same as בחרבכם; (Exodus 6:26) “by their hosts (על צבאותם), which is the same as בצבאותם.
