'Warfare' in the Bible
He will judge between the nations, and will render verdicts for the benefit of many. "They will beat their swords into plowshares, and their spears into pruning hooks; nations will not raise swords against nations, and they will not learn warfare anymore.
This happened in the days of Ahaz, son of Jotham, son of Uzziah, king of Judah. Rezin, king of Aram, and Pekah, son of Remaliah, king of Israel, went up [to] Jerusalem for warfare against it, but he was not able to fight against it.
And they [of Babylon] shall be dismayed and terrified, pangs and sorrows shall take hold of them; they shall be in pain as a woman in childbirth. They will gaze stupefied and aghast at one another, their faces will be aflame [from the effects of the unprecedented warfare].
Speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned: for she hath received of the LORD'S hand double for all her sins.
