'War' in the Bible

But of late my people is risen up as an enemy: ye strip off the mantle with the garment from them that pass by securely, that are averse from war.

Thus saith Jehovah concerning the prophets that cause my people to err, that bite with their teeth, and cry, Peace! but whoso putteth not into their mouths they prepare war against him:

And he shall judge among many peoples, and reprove strong nations, even afar off; and they shall forge their swords into ploughshares, and their spears into pruning-knives: nation shall not lift up sword against nation, neither shall they learn war any more.
