'Army' in the Bible

And suddenly there was with the angel a multitude of the heavenly army, praising God and saying,

And those who served in the army were also asking him, saying, "What should we also do?" And he said to them, "Extort from no one, and do not blackmail [anyone], and be content with your pay."

And I saw the beast and the kings of the earth and their armies assembled to make war with the one who is seated on the horse and with his army.
