   species are brown in summer, and turn white in winter; others
   are brown at all seasons.

from Easton's 1897 Bible Dictionary
Weasel
(Heb. holedh), enumerated among unclean animals (Lev. 11:29).
Some think that this Hebrew word rather denotes the mole (Spalax
typhlus) common in Palestine. There is no sufficient reason,
however, to depart from the usual translation. The weasel tribe
are common also in Palestine.
