'Hosts' in the Bible

And Elisha said, As Jehovah of hosts liveth, before whom I stand, surely, were it not that I regard the presence of Jehoshaphat the king of Judah, I would not look toward thee nor see thee.

For out of Jerusalem shall go forth a remnant, And out of mount Zion they that escape: The zeal of Jehovah of hosts shall do this.
