'Warrior' in the Bible

There was fierce war with the Philistines all the days of Saul. So whenever Saul saw anyone who was a warrior or a brave individual, he would conscript him.

One of his attendants replied, "I have seen a son of Jesse in Bethlehem who knows how to play the lyre. He is a brave warrior and is articulate and handsome, for the Lord is with him."

But Saul replied to David, "You aren't able to go against this Philistine and fight him! You're just a boy! He has been a warrior from his youth!"

Then Saul said to David, "Here's my oldest daughter, Merab. I want to give her to you in marriage. Only be a brave warrior for me and fight the battles of the Lord." For Saul thought, "There's no need for me to raise my hand against him. Let it be the hand of the Philistines!"
