1 Samuel 17:10

Defy. Literally, “reproach” or “taunt,” that is, for not accepting Goliath’s challenge. He branded the men of Israel as being most unsportsmanlike and cowardly. The wadi separating the opposing forces was so difficult to cross that if either side ventured a frontal attack it was almost sure of defeat. The Philistines were so confident that no physical match could be found for their champion that they proposed to decide the battle by single combat. This challenge continued daily for more than a month (v. 16).
