Acts 1:9-14

9And when he had said these things, as they were looking, he was taken up; and a cloud received him out of their sight. 10And while they were looking stedfastly into heaven as he went, behold two men stood by them in white apparel; 11who also said, Ye men of Galilee, why stand ye looking into heaven? this Jesus, who was received up from you into heaven, shall so come in like manner as ye beheld him going into heaven.

12Then returned they unto Jerusalem from the mount called Olivet, which is nigh unto Jerusalem, a sabbath day’s journey off. 13And when they were come in, they went up into the upper chamber, where they were abiding; both Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphæus, and Simon the Zealot, and Judas the son of James. 14These all with one accord continued stedfastly in prayer, with the women, and Mary the mother of Jesus, and with his brethren.
