'War' in the Bible

“But lately My people have stood up as an enemy [and have made Me their antagonist].You strip the ornaments off the garmentOf those unsuspecting passers-by,Like those returned from war.

Thus says the Lord concerning the [false] prophets who lead my people astray;When they have something good to bite with their teeth,They call out, “Peace,”But against the one who gives them nothing to eat,They declare a holy war.

And He will judge between many peoplesAnd render decisions for strong and distant nations.Then they shall hammer their swords into plowsharesAnd their spears into pruning hooks [so that the implements of war may become the tools of agriculture];Nation shall not lift up sword against nation,Nor shall they ever again train for war.
