'War' in the Bible

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

Now the war against the Philistines was severe all the days of Saul; and when Saul saw any mighty man or any valiant man, he attached him to his staff.

So David arose early in the morning and left the flock with a keeper and took the supplies and went as Jesse had commanded him. And he came to the circle of the camp while the army was going out in battle array shouting the war cry.

So David went out wherever Saul sent him, and prospered; and Saul set him over the men of war. And it was pleasing in the sight of all the people and also in the sight of Saul’s servants.

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

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

Now it came about in those days that the Philistines gathered their armed camps for war, to fight against Israel. And Achish said to David, “Know assuredly that you will go out with me in the camp, you and your men.”

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