'Fighting' in the Bible

For Saul and they and all the men of Israel are in the valley of Elah, fighting with the Philistines.”

Then they told David, saying, “Behold, the Philistines are fighting against Keilah and are plundering the threshing floors.”

Please forgive the transgression of your maidservant; for the Lord will certainly make for my lord an enduring house, because my lord is fighting the battles of the Lord, and evil will not be found in you all your days.

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