In 2 Kings 10:19, Jehu acts 'with cunning'—employing deception to lure the worshipers of Baal into a trap so he can slaughter them. The word conveys insidiousness, a sly, underhanded approach to achieving one's goal. Spanish uses 'con astucia' (with cunning/cleverness), French 'avec rusé' (with craftiness). While Jehu's goal (destroying Baal worship) is presented as divinely sanctioned, the method involves deliberate deceit—pretending to honor Baal in order to gather all his worshipers in one place for execution. The term captures the morally ambiguous use of trickery for a 'righteous' end.
