'War' in the Bible

Lately my people have acted like an enemy you strip travelers who thought they were as secure as those who return from war.

"This is what the LORD says about the prophets who are causing my people to go astray, who are calling out "Peace' when they're being fed, but who declare war against those who won't feed them:

And he will judge among many people, rebuking strong nations far away; and they will reshape their swords as plowshares and their spears as pruning hooks. No nation will threaten another, nor will they train for war anymore.
