The Upper Room

Acts 1:12-14

12  Then returned they unto Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day's journey. 
13  And when they were come in, they went up into an upper room, where abode both Peter, and James, and John, and Andrew, Philip, and Thomas, Bartholomew, and Matthew, James the son of Alphaeus, and Simon Zelotes, and Judas the brother of James. 
14  These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren.
