'Army' in the Bible

Now [Saul’s cousin] 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, “Abner the son of Ner came to the king, and he has sent him away, and he has gone in peace.”

And when you hear the sound of marching in the tops of the balsam trees, then you shall pay attention and act promptly, for at that time the Lord will have gone out before you to strike the army of the Philistines.”

Joab the son of Zeruiah was [commander] over the army; Jehoshaphat the son of Ahilud was recorder (secretary);

When David heard about it, he sent Joab and the entire army, the strong and brave men.

Hadadezer sent word and brought out the Arameans who were beyond the River [Euphrates]; 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 Aramean charioteers and 40,000 horsemen, and struck Shobach the commander of their army, and he died there.

Absalom put Amasa in command of the army instead of Joab. Now Amasa was the son of a man named Ithra the Israelite, who had married Abigail the daughter of Nahash, [the half sister of David and] the sister of Zeruiah, Joab’s mother.

Then David sent the army out, a third under the command of Joab, a third under Abishai the son of Zeruiah, Joab’s brother, and a third under the command of Ittai the Gittite. And the king said to the men, “I myself will certainly go out [to fight] with you.”

Then the king said to them, “I will do whatever seems best to you.” So the king stood beside the gate [of Mahanaim], and all the army went out in groups of hundreds and of thousands.

So the men went out into the field against Israel, and the battle was fought in the forest of Ephraim.

Say to Amasa [the commander of Absalom’s troops], ‘Are you not my bone and my flesh? May God do so to me, and more also, if you will not be commander of my army from now on in place of Joab.’”

So the three mighty men broke through the camp of the Philistines, and drew water from the well of Bethlehem by the gate, and carried and brought it to David. But he would not drink it, but poured it out [in worship] to the Lord.

Nevertheless, the king’s word prevailed against Joab and the commanders of the army. So they went from the king’s presence to take a census of the people of Israel.
