Acts 1:12-15

¹²Then the disciples went back to Jerusalem from the Mount of Olives which is about a Sabbath day's walk from Jerusalem.

¹³When they arrived, they went upstairs to the upper room where they were staying: Peter, John, James and Andrew; Philip and Thomas; Bartholomew and Matthew; James the son of Alphaeus, Simon the Zealot, and Judas the son of James.

¹⁴They all joined together in prayer, together with the women and Mary, Jesus' mother, and his brothers.

¹⁵At this time Peter stood up and addressed a crowd of around one hundred and twenty believers who had gathered together.
