'Fighting' in the Bible

They are with Saul and the whole Israelite army in the valley of Elah, fighting with the Philistines."

Then Saul clothed David with his own fighting attire and put a bronze helmet on his head. He also put body armor on him.

David strapped on his sword over his fighting attire and tried to walk around, but he was not used to them. David said to Saul, "I can't walk in these things, for I'm not used to them." So David removed them.

They told David, "The Philistines are fighting in Keilah and are looting the threshing floors."

Samuel said to Saul, "Why have you disturbed me by bringing me up?" Saul replied, "I am terribly troubled! The Philistines are fighting against me and God has turned away from me. He does not answer me -- not by the prophets nor by dreams. So I have called on you to tell me what I should do."

Now the Philistines were fighting against Israel. The men of Israel fled from the Philistines and many of them fell dead on Mount Gilboa.
