'Army' in the Bible

and what He did to the army of Egypt, to its horses and its chariots, when He made the water of the Red Sea engulf them as they pursued you, and how the Lord completely destroyed them;

“When you go out to battle against your enemies and see horses and chariots and people more numerous than you, do not be afraid of them; for the Lord your God, who brought you up from the land of Egypt, is with you.

“When a man takes a new wife, he shall not go out [to fight] with the army nor be charged with any duty; he shall be free at home for one year and shall bring happiness to his wife whom he has taken.
