'Hosts' in the Bible

And Elisha saith, 'Jehovah of Hosts liveth, before whom I have stood; for unless the face of Jehoshaphat king of Judah I am lifting up, I do not look unto thee, nor see thee;

For from Jerusalem goeth out a remnant, And an escape from mount Zion; The zeal of Jehovah of Hosts doth this.
