'Warfare' in the Bible

It happened in those days, that the Philistines gathered their armies together for warfare, to fight with Israel. Achish said to David, "Know assuredly that you shall go out with me in the army, you and your men."

You renew your witnesses against me, and increase your indignation on me. Changes and warfare are with me.

If a man dies, shall he live again? All the days of my warfare would I wait, until my release should come.

"Speak comfortably to Jerusalem; and call out to her that her warfare is accomplished, that her iniquity is pardoned, that she has received of Yahweh's hand double for all her sins."

In the third year of Cyrus king of Persia a thing was revealed to Daniel, whose name was called Belteshazzar; and the thing was true, even a great warfare: and he understood the thing, and had understanding of the vision.
