In divine dealings with Israel and the nations, we don't really see divine armies employed much. More often foreign armies are employed in order to punish Israel and bring her into exile.
We do see angelic armies, though, as well, at least as a vision.
Is this designation intended as "divine warrior" imagery, speaking metaphorically of G-d's greatness, metaphor of his supreme control of nations or a literal military maintained in heaven which is intended to say that "the cops are watching"?
Put another way, given divine omnipotence, how metaphorically should we understand "angel armies", both in our conception of the divine realm and in regard to divine interventions in the affairs of men?
To clarify even further, is "ruler of armies" simply anthropomorphism?
1 Samuel 1: 3And that man was wont to go up from his city from appointed time to appointed time, to prostrate himself and to slaughter (peace offerings) to the Lord of Hosts in Shiloh, and there the two sons of Eli, Hophni and Phinhas, were serving the Lord.
