* hired.
  18:4  Ex 14:9  Jud 4:3  1Sa 13:5  2Ch 14:9  Ps 20:7-9 
 * thirty.
   Thirty-two thousand soldiers, exclusive of the thousand send
   by the Maachah, are mentioned in the parallel passage (2; Sa
   10:6;) but of chariots or cavalry there is no mention; and the
   number of chariots stated here is prodigious, and beyond all
   credibility.  But as the word {raichev} denotes not only a
   chariot, but a rider, (see Isa 21:7,) it ought most probably
   to be rendered here, in a collective sense, cavalry; and then
   the number of troops will exactly agree with the passage in
   Samuel.  It is probable that they were a kind of auxiliary
   troops who were usually mounted on horses, or in chariots, but
   who occasionally served as foot-soldiers.

 * the king of Maachah.
   This variation exists only in the translation, the original
   being the same in both places, {melech m(8461)chah,} "the king of
   Maachah."

 * king Maachah.  Medeba.
