Defy (1):
de-fi' (charaph, za`am): In 1 Samuel 17:10, 1 Samuel 17:25, 1 Samuel 17:26, 1 Samuel 17:36, 1 Samuel 17:45 (the story of David and Goliath) and kindred passages, this word is used in its most familiar sense-"to taunt," "challenge to combat" (Hebrew charaph). In Numbers 23:7, Numbers 23:8 "denounce" would be a better translation than "defy" (Hebrew za`am).
