'Warrior' in the Bible

There was intense fighting against the Philistines during Saul's entire reign, and whenever Saul discovered a strong or valiant warrior, he would enlist him for service.

One of the young men answered, “I have seen a son of Jesse of Bethlehem who knows how to play the lyre. He is also a valiant man, a warrior, eloquent, handsome, and the Lord is with him.”

But Saul replied, “You can’t go fight this Philistine. You’re just a youth, and he’s been a warrior since he was young.”

Saul told David, “Here is my oldest daughter Merab. I’ll give her to you as a wife, if you will be a warrior for me and fight the Lord’s battles.” But Saul was thinking, “My hand doesn’t need to be against him; let the hand of the Philistines be against him.”
