'Army' in the Bible

And he said, No; for as captain of the army of Jehovah am I now come. Then Joshua fell upon his face to the earth, and worshipped, and said to him, What saith my lord unto his servant?

And the captain of Jehovah's army said to Joshua, Loose thy sandal from off thy foot: for the place whereon thou standest is holy. And Joshua did so.
