Pelethites: Mentioned always along with the Cherethites, and only in the time of
David. The word probably means "runners" or "couriers," and may
denote that while forming part of David's bodyguard, they were also
sometimes employed as couriers
(2 Samuel 8:18; 20:7,23; 1 Kings 1:38,44)
(1 Chronicles 18:17) Some, however, think that these are the names simply of
two Philistine tribes from which David selected his body-guard. They
are mentioned along with the Gittites
(2 Samuel 15:18) another body of
foreign troops whom David gathered round him.
