'Brave' in the Bible

Warfare was severe against [the] Philistines all the days of Saul. Whenever Saul saw {anyone who was a mighty warrior} or {any brave man}, he {conscripted him into his service}.

One of the servants answered and said, "Look, I have seen a son of Jesse the Bethlehemite [who is] skillful in playing a stringed instrument, a {brave man, a warrior, prudent in speech, and handsome}. And Yahweh [is] with him."

Then Saul said to David, "Here [is] my older daughter Merab. I will give her to you as [your] wife. Only be {a brave warrior} for me and fight the battles of Yahweh." For Saul thought, "My hand will not be against him, but let the hand of [the] Philistines be against him."
