The plural form typically means armies or hosts, and is most famous in the divine title "LORD of Hosts," which pictures God as the commander of heavenly and earthly armies. This occurrence retains that theological weight, emphasizing God's sovereign power. The term can refer to angelic hosts, Israel's armies, or even the stars—all under divine command. It's a militaristic image, but one that assures believers of God's overwhelming might in defense of his people.
