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, Matt 6:5, Matt 6:16). “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.
