'Armies' in the Bible

And Benhadad hearkened unto king Asa, and sent the captains of his armies against the cities of Israel; and they smote Ijon, and Dan, and Abelmaim, and all the store cities of Naphtali.

After this Sennacherib the king of Assyria sent his servants to Jerusalem (now he and all his armies with him [were] against Lachish) to Hezekiah king of Judah and to all of Judah that [was] in Jerusalem, saying,

He re-established the high places that his father Hezekiah had demolished, he built altars to the Baals, erected Asherim, and worshipped and served the armies of heaven.

He built altars for all the armies of heaven in the two courtyards of the LORD's Temple.
