'War' in the Bible

During the reign of Jotham's son Ahaz, Uzziah's grandson, king of Judah, King Rezin of Aram and Remaliah's son Pekah, king of Israel, approached Jerusalem and waged war against it, but they could not mount an attack against it.

You have increased the nation; you have increased its joy; they rejoice in your presence as they rejoice at the harvest, as they are glad when they're dividing the spoils of war.

The LORD marches out like a warrior; he stirs up his rage like a man of war; he makes his anger heard; he shouts aloud; he declares his mastery over his enemies:

so he drenched him with the heat that is his anger, the violence of war. It enveloped him in flames, but still he had no insight. It burned him up, but he didn't take it to heart."
