tsa.va denotes collective hosts, chiefly in the divine designation used of the LORD and occasionally of organized armies.

The plural form chiefly occurs within the designation of the LORD in declarations, prayer, worship, judgment, and promised action. A smaller group of verses uses it for organized military bodies, including armies and their rulers.

1. Hosts in the LORD's designation · dominant

   The plural absolute form appears with the LORD across divine speech, prayer, and public confession. In 1 Samuel 17:45 the APB renders David's appeal as coming “in the name of the LORD of Hosts” while identifying him with “the God of the ranks of Israel”; in Haggai 2:6 the same designation introduces the announcement that heaven, earth, sea, and dry land will be shaken. Amos 6:14 likewise places it in the declaration of a nation raised against Israel.

2. Organized armies or military divisions · rare

   In the plural absolute form, the term can refer to human military groupings. Deuteronomy 20:9 concerns “the commanders of the armies,” and 1 Chronicles 27:3 identifies a man as head over rulers of the Hosts for the first month.

In the Anselm Project Bible: Across the supplied verses, the APB most often presents the form in “the LORD of Hosts” or “the LORD God of Hosts.” In Deuteronomy 20:9 and 1 Chronicles 27:3 it instead renders the surrounding military context with “armies” and “Hosts”.
