Easton's 1897 Bible Dictionary:

Hypocrite
   one who puts on a mask and feigns himself to be what he is not;
   a dissembler in religion. Our Lord severely rebuked the scribes
   and Pharisees for their hypocrisy (Matt. 6:2, 5, 16). "The
   hypocrite's hope shall perish" (Job 8:13). The Hebrew word here
   rendered "hypocrite" rather means the "godless" or "profane," as
   it is rendered in Jer. 23:11, i.e., polluted with crimes.


The Devil's Dictionary (1881-1906):

HYPOCRITE, n.  One who, profession virtues that he does not respect
secures the advantage of seeming to be what he despises.
