'Army' in the Bible

Abner son of Ner, commander of Saul’s army, took Saul’s son Ish-bosheth and moved him to Mahanaim.

When Joab and all his army arrived, Joab was informed, “Abner son of Ner came to see the king, the king dismissed him, and he went in peace.”

When King Toi of Hamath heard that David had defeated the entire army of Hadadezer,

Joab son of Zeruiah was over the army;Jehoshaphat son of Ahilud was court historian;

Hadadezer sent messengers to bring the Arameans who were across the Euphrates River, and they came to Helam with Shobach, commander of Hadadezer’s army, leading them.

But the Arameans fled before Israel, and David killed 700 of their charioteers and 40,000 foot soldiers. He also struck down Shobach commander of their army, who died there.

Now Absalom had appointed Amasa over the army in Joab’s place. Amasa was the son of a man named Ithra the Israelite; Ithra had married Abigail daughter of Nahash. Abigail was a sister to Zeruiah, Joab’s mother.

And tell Amasa, ‘Aren’t you my flesh and blood? May God punish me and do so severely if you don’t become commander of the army from now on instead of Joab!’”

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

So the king said to Joab, the commander of his army, “Go through all the tribes of Israel from Dan to Beer-sheba and register the troops so I can know their number.”

Yet the king’s order prevailed over Joab and the commanders of the army. So Joab and the commanders of the army left the king’s presence to register the troops of Israel.
