'Waging' in the Bible

Samuel told Saul, "Why did you disturb me by bringing me up?" Saul said, "I'm in great distress. The Philistines are waging war against me. God has departed from me and won't answer me anymore, either by messages written by the hand of the prophets or by dreams. So I've summoned you to tell me what I should do."

His sons will prepare for war, assembling an army of considerable force. One of them will come on forcefully, overflowing, passing through, and waging war up to his own fortress.

Then the LORD will go out to battle against those nations, waging war as in a day of battle.

but I see in my body a different principle waging war with the Law in my mind and making me a prisoner of the law of sin that exists in my body.
