Acts 1:9-14

And after He said these things, He was caught up as they looked on, and a cloud took Him up out of their sight. While they were looking intently into the sky as He was going, two men in white clothing suddenly stood beside them, who said, “Men of Galilee, why do you stand looking into the sky? This [same] Jesus, who has been taken up from you into heaven, will return in just the same way as you have watched Him go into heaven.” Then the disciples returned to Jerusalem from the mount called Olivet (Olive Grove), which is near Jerusalem, [only] a Sabbath day’s journey (less than one mile) away. When they had entered the city, they went upstairs to the upper room where they were staying [indefinitely]; that is, Peter, and John and [his brother] James, and Andrew, Philip and Thomas, Bartholomew (Nathanael) and Matthew, James the son of Alphaeus, and Simon the Zealot, and Judas (Thaddaeus) the son of James. All these with one mind and one purpose were continually devoting themselves to prayer, [waiting together] along with the women, and Mary the mother of Jesus, and with His brothers.
