'Fighting' in the Bible

David heard about it and sent Joab and all the fighting men.

In the letter he wrote:Put Uriah at the front of the fiercest fighting, then withdraw from him so that he is struck down and dies.

“Your servant had two sons. They were fighting in the field with no one to separate them, and one struck the other and killed him.

Joab gave the king the total of the registration of the troops. There were 800,000 fighting men from Israel and 500,000 men from Judah.
