'War' in the Bible

I will cut off the chariot from EphraimAnd the horse from Jerusalem;And the bow of war will be cut off.And He will speak peace to the nations;And His dominion will be from sea to sea,And from the River to the ends of the earth.

Now this will be the plague with which the Lord will strike all the peoples who have gone to war against Jerusalem; their flesh will rot while they stand on their feet, and their eyes will rot in their sockets, and their tongue will rot in their mouth.
