At Belshazzar's feast, the king and his guests drank from vessels taken from where?

Answer: The temple in Jerusalem

Belshazzar had the gold and silver vessels that Nebuchadnezzar took from the temple in Jerusalem brought in, and they drank from them.

“Under the influence of the wine, Belshazzar gave orders to bring in the gold and silver vessels that Nebuchadnezzar his father had taken from the temple in Jerusalem, so that the king could drink from them, along with his nobles, his wives, and his concubines.”— Daniel 5:2 (BSB)
