'Army' in the Bible

But they forgot the Lord their God, so He sold them into the hand of Sisera, captain of the army of Hazor, and into the hand of the Philistines and into the hand of the king of Moab, and they fought against them.

The name of Saul’s wife was Ahinoam the daughter of Ahimaaz. And the name of the captain of his army was Abner the son of Ner, Saul’s uncle.

So David arose early in the morning and left the flock with a keeper and took the supplies and went as Jesse had commanded him. And he came to the circle of the camp while the army was going out in battle array shouting the war cry.

Israel and the Philistines drew up in battle array, army against army.

As he was talking with them, behold, the champion, the Philistine from Gath named Goliath, was coming up from the army of the Philistines, and he spoke these same words; and David heard them.

This day the Lord will deliver you up into my hands, and I will strike you down and remove your head from you. And I will give the dead bodies of the army of the Philistines this day to the birds of the sky and the wild beasts of the earth, that all the earth may know that there is a God in Israel,

Now when Saul saw David going out against the Philistine, he said to Abner the commander of the army, “Abner, whose son is this young man?” And Abner said, “By your life, O king, I do not know.”

David then arose and came to the place where Saul had camped. And David saw the place where Saul lay, and Abner the son of Ner, the commander of his army; and Saul was lying in the circle of the camp, and the people were camped around him.

Moreover the Lord will also give over Israel along with you into the hands of the Philistines, therefore tomorrow you and your sons will be with me. Indeed the Lord will give over the army of Israel into the hands of the Philistines!”

Then Achish called David and said to him, “As the Lord lives, you have been upright, and your going out and your coming in with me in the army are pleasing in my sight; for I have not found evil in you from the day of your coming to me to this day. Nevertheless, you are not pleasing in the sight of the lords.
