tsa.va describes serving in an assigned duty, often in military action, and can also describe mustering people.

The attested uses most often occur in contexts of military engagement or action against a place or people; they also describe assigned work at the tent of meeting and, in Hiphil participles, the mustering of people for an army.

1. Military engagement or action · dominant

   Qal forms occur with nations, soldiers, and peoples acting in conflict: in Numbers 31:7 the APB renders the clause "They served against Midian," while Numbers 31:42 refers to men "who served in the army." Isaiah 29:7, Isaiah 29:8, and Isaiah 31:4 place the forms in scenes involving nations and Mount Zion, and Zechariah 14:12 describes peoples who "wage war against Jerusalem."

2. Assigned service at the tent of meeting · common

   Qal feminine plural participles identify women at the entrance of the tent of meeting in Exodus 38:8 and 1 Samuel 2:22; the APB calls them women "who served." In Numbers 4:23 and Numbers 8:24, Qal infinitive constructs occur with coming to perform work or duty in the tent's service.

3. Mustering people for the army · occasional

   The Hiphil active participle identifies an army official or secretary whose task is to muster the people of the land in 2 Kings 25:19 and Jeremiah 52:25. The APB renders that task "mustered the people of the land" in both verses.

   2 Kings 25:19Jeremiah 52:25

In the Anselm Project Bible: The APB variously presents these clauses with "served," "service," "duty," "mustered," and "wage war," reflecting their different verse contexts. Because the APB is a whole-verse translation, these renderings do not by themselves isolate the term's exact contribution in every clause.
