'War' in the Bible

only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing of it:

It happened after a while, that the children of Ammon made war against Israel.

It was so, that when the children of Ammon made war against Israel, the elders of Gilead went to get Jephthah out of the land of Tob;

I therefore have not sinned against you, but you do me wrong to war against me. Yahweh, the Judge, be judge this day between the children of Israel and the children of Ammon."

There set forth from there of the family of the Danites, out of Zorah and out of Eshtaol, six hundred men girt with weapons of war.

The six hundred men girt with their weapons of war, who were of the children of Dan, stood by the entrance of the gate.

The five men who went to spy out the land went up, and came in there, and took the engraved image, and the ephod, and the teraphim, and the molten image: and the priest stood by the entrance of the gate with the six hundred men girt with weapons of war.

The men of Israel, besides Benjamin, were numbered four hundred thousand men who drew sword: all these were men of war.
