'Fighting' in the Bible

The descendants of Benjamin rallied after Abner, and they became as one fighting group and stood on the top of a certain hill.

When the {Ammonites} saw that Aram had fled, they fled from before Abishai and entered the city. Then Joab returned from [fighting] against the {Ammonites} and came to Jerusalem.

He had written in the letter, "Put Uriah in the front, in the face of the fiercest fighting, then draw back from behind him so that he may be struck down and die."
