'Army' in the Bible

This man was taken of the Jews, and should have been killed of them: then came I with an army, and rescued him, having understood that he was a Roman.

And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.

And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
