'Fighting' in the Bible

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

Moreover Uzziah had an host of fighting men, that went out to war by bands, according to the number of their account by the hand of Jeiel the scribe and Maaseiah the ruler, under the hand of Hananiah, one of the king's captains.

{To the chief Musician upon Jonathelemrechokim, Michtam of David, when the Philistines took him in Gath.} Be merciful unto me, O God: for man would swallow me up; he fighting daily oppresseth me.
