'War' in the Bible

and he will appoint them to him for captains of thousands, and captains of fifties; and [he will set some] to plow his ground, and to reap his harvest, and to make his instruments of war, and the instruments of his chariots.

There was severe war against the Philistines all the days of Saul: and when Saul saw any mighty man, or any valiant man, he took him to him.

Then one of the young men answered, and said, "Behold, I have seen a son of Jesse the Bethlehemite, who is skillful in playing, a mighty man of valor, a man of war, prudent in speech, and a comely person; and Yahweh is with him."

Saul said to David, "You are not able to go against this Philistine to fight with him; for you are but a youth, and he a man of war from his youth."

David went out wherever Saul sent him, [and] behaved himself wisely: and Saul set him over the men of war, and it was good in the sight of all the people, and also in the sight of Saul's servants.

There was war again. David went out, and fought with the Philistines, and killed them with a great slaughter; and they fled before him.

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

Samuel said to Saul, "Why have you disturbed me, to bring me up?" Saul answered, "I am very distressed; for the Philistines make war against me, and God has departed from me, and answers me no more, neither by prophets, nor by dreams. Therefore I have called you, that you may make known to me what I shall do."
