'Army' in the Bible

and what He did to Egypt’s army, to its horses and its chariots, when He made the water of the Red Sea to engulf them while they were pursuing you, and the Lord completely destroyed them;

“When you go out as an army against your enemies, you shall keep yourself from every evil thing.

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