'Army' in the Bible

And the captain of the Lord's army said to Joshua, Take off your shoes from your feet, for the place where you are is holy. And Joshua did so.

So all the people were in their places, the army on the north side of the town and the secret force on the west; and that night Joshua went down into the valley.

So Joshua went up from Gilgal with all his army and all his men of war.

But do you, without waiting, go after their army, attacking them from the back; do not let them get into their towns, for the Lord your God has given them into your hands.
