'Army' in the Bible

But Abner the son of Ner, commander of Saul’s army, had taken Ish-bosheth the son of Saul and brought him over to Mahanaim.

When Joab and all the army that was with him arrived, they told Joab, saying, “Abner the son of Ner came to the king, and he has sent him away, and he has gone in peace.”

It shall be, when you hear the sound of marching in the tops of the balsam trees, then you shall act promptly, for then the Lord will have gone out before you to strike the army of the Philistines.”

Now when Toi king of Hamath heard that David had defeated all the army of Hadadezer,

Joab the son of Zeruiah was over the army, and Jehoshaphat the son of Ahilud was recorder.

When David heard of it, he sent Joab and all the army, the mighty men.

And Hadadezer sent and brought out the Arameans who were beyond the River, and they came to Helam; and Shobach the commander of the army of Hadadezer led them.

But the Arameans fled before Israel, and David killed 700 charioteers of the Arameans and 40,000 horsemen and struck down Shobach the commander of their army, and he died there.

Absalom set Amasa over the army in place of Joab. Now Amasa was the son of a man whose name was Ithra the Israelite, who went in to Abigail the daughter of Nahash, sister of Zeruiah, Joab’s mother.

Say to Amasa, ‘Are you not my bone and my flesh? May God do so to me, and more also, if you will not be commander of the army before me continually in place of Joab.’”

Now Joab was over the whole army of Israel, and Benaiah the son of Jehoiada was over the Cherethites and the Pelethites;

The king said to Joab the commander of the army who was with him, “Go about now through all the tribes of Israel, from Dan to Beersheba, and register the people, that I may know the number of the people.”

Nevertheless, the king’s word prevailed against Joab and against the commanders of the army. So Joab and the commanders of the army went out from the presence of the king to register the people of Israel.
