Sebasma denotes a worshiped object, whether among observed cultic objects or as something set above all called god.

The two occurrences show a worshiped object in a plural setting of observed objects and in a singular setting of something placed beneath a figure’s self-exaltation above all called god.

1. Worshiped objects in public observation · dominant

   In Acts 17:23, the accusative plural form occurs as the speaker passes through and observes the city’s objects; the APB renders the clause "observed your objects of worship" and then mentions an altar inscribed "To an unknown god."

   Acts 17:23
2. A worshiped object set below self-exaltation · occasional

   In 2 Thessalonians 2:4, the accusative singular form occurs in the statement that a figure exalts himself above all that is called god or object of worship; the APB renders the wider clause "He opposes and exalts himself above all that is called god or object of worship."

   2 Thessalonians 2:4

In the Anselm Project Bible: The APB uses "objects of worship" in Acts 17:23 and "object of worship" in 2 Thessalonians 2:4. These phrases confirm the clauses’ presentation rather than isolate each token mechanically.
