'War' in the Bible

He will appoint them for himself to be commanders over thousands and over fifties, and some to do his plowing and to reap his harvest and to make his implements of war and equipment for his chariots.

Now the war against the Philistines was severe (brutal, relentless) all the days of Saul; and whenever Saul saw any mighty or courageous man, he recruited him for his staff.

One of the young men said, “Behold, I have seen a son of Jesse the Bethlehemite who is a skillful musician, a brave and competent man, a warrior, discerning (prudent, eloquent) in speech, and a handsome man; and the Lord is with him.”

So David went out wherever Saul sent him, and he acted wisely and prospered; and Saul appointed him over the men of war. And it pleased all the people and also Saul’s servants.

Then there was war again, and David went out and fought with the Philistines and defeated them with a great slaughter, and they fled before him.

So Saul summoned all the people (soldiers) for war, to go down to Keilah to besiege David and his men.

In those days the Philistines gathered their forces for war to fight against Israel. Achish said to David, “Understand for certain that you and your men will go out with me to battle.”

Then Samuel said to Saul, “Why have you disturbed me by bringing me up?” Saul answered, “I am greatly distressed; for the Philistines are making war against me, and God has left me and no longer answers me, either through prophets or by dreams; therefore I have called you to make known to me what I should do.”
