'Upper Room' in the Bible

On entering the city they went to the upper room where they were in the habit of meeting; there were Peter, John, James, Andrew, Philip and Thomas, Bartholomew and Matthew, James (the son of Alphaeus) and Simon who had been a Zealot, with Judas the son of James.

She happened to take ill and die at this time, and after washing her body they laid it in an upper room.

(there were plenty of lamps in the upper room where we met).
