ACTS 1:9-11

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;

¹¹which also said, Ye men of Galilee, why stand ye looking into heaven? this Jesus, which was received up from you into heaven, shall so come in like manner as ye beheld him going into heaven.
