'Fighting' in the Bible

Now Saul and they and all the men of Israel [were] in the valley of Elah fighting [the] Philistines.

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

Then David strapped on his sword over his fighting attire, but he tried in vain to walk [around], for he was not trained to use [them]. So David said to Saul, "I am not able to walk with these, because I am not trained to use [them]." So David removed them.

Jonathan stripped off the robe {that he was wearing} and gave it to David, along with his fighting attire, and even his sword, his bow, and his belt.

Now they told David, "Look, [the] Philistines [are] fighting in Keilah and they [are] raiding the threshing floors."

Please forgive the transgression of your female servant, because Yahweh will certainly make a lasting house for my lord, because my lord [is] fighting the battles of Yahweh, and evil will not be found in you {as long as you live}.

Now [the] Philistines [were] fighting against Israel, and the men of Israel fled before [the] Philistines, and they fell slain on Mount Gilboa.
