Acts 1:9-14

9And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. 10And while they looked steadfastly toward heaven as he went up, behold, two men stood by them in white apparel; 11Who also said, Ye men of Galilee, why stand ye gazing up to heaven? this same Jesus, who is taken from you into heaven, shall so come in like manner as ye have seen him go into heaven.

12Then they returned to Jerusalem from the mount called Olivet, which is from Jerusalem a sabbath day’s journey. 13And when they had come in, they went 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. 14These all continued with one accord in prayer and supplication, with the women, and Mary the mother of Jesus, and with his brethren.
