Luke 24:50-53 - The Ascension
6 They therefore, having come together, asked him, saying, Lord, art thou at this time about to restore the kingdom to Israel?
7 But he said to them, It belongeth not to you to know times or seasons, which the Father appointed by his own authority. 8 But ye will receive power when the Holy Spirit hath come upon you; and ye will be my witnesses, both in Jerusalem and in all Judaea, and in Samaria, and to the end of the earth.
9 And having thus spoken, while they beheld, he was taken up; and a cloud received him out of their sight. 10 And while they were looking earnestly into heaven as he went up, lo! two men stood by them in white apparel, 11 who said, Men of Galilee, why stand ye gazing up into heaven? This Jesus, who hath been taken up from you into heaven, will come in the same manner in which ye beheld him going into heaven.
