a.tsa.rah denotes a formal gathering, especially one called in connection with a feast, fast, or prescribed observance.

The attested noun denotes a formal gathering in worship-related settings: an eighth-day observance in Leviticus 23:36 and Numbers 29:35, a gathering called with a fast in Joel 1:14 and Joel 2:15, and gatherings mentioned among feasts in Amos 5:21. Its singular and plural forms occur in these settings, while the APB does not clearly isolate its contribution in Jeremiah 9:1.

   The singular absolute form occurs in clauses concerning an eighth-day observance in Leviticus 23:36 and Numbers 29:35; in both verses the APB renders the surrounding clause with an assembly and a prohibition of work. In Joel 1:14 and Joel 2:15, the same singular form stands in calls to consecrate a fast and call a gathering; Amos 5:21 has the plural construct form in a statement rejecting feasts and gatherings.

In the Anselm Project Bible: Across the occurrences, the APB commonly presents the surrounding clauses with “assembly,” and in Nehemiah 8:18 with “solemn assembly.” Its wording cannot always isolate the noun's specific contribution; Jeremiah 9:1 does not visibly render it in the supplied English.
