Acts 1:9-12

And when he had said these things, as they were looking, he was taken up; and a cloud received him out of their sight. And while they were looking stedfastly into heaven as he went, behold two men stood by them in white apparel; who 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. Then returned they unto Jerusalem from the mount called Olivet, which is nigh unto Jerusalem, a sabbath day’s journey off.
