'War' in the Bible

But {recently} my people have risen up as an enemy; from before the cloak you strip off the robe from those passing by [in] confidence, returning [from] war.

Thus says Yahweh concerning the prophets who are leading my people astray, who are biting with their teeth and proclaim, "Peace," but whoever puts nothing into their mouths they declare war against.

And he will judge between many peoples and will arbitrate for strong nations far away; and they will beat their swords into plowshares and their spears into pruning hooks; nation will not lift up a sword against a nation, and they will no longer learn war.
