Acts 1:10

7 He said to them, "It isn`t for you to know times or seasons which the Father has set within His own authority.

8 But you will receive power when the Holy Spirit has come on you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth."

9 When he had said these things, as they were looking, he was taken up, and a cloud received him out of their sight.

10 While they were looking steadfastly into the sky as he went, behold, two men stood by them in white clothing,

11 who also said, "You men of Galilee, why do you stand looking into the sky? This Jesus, who was received up from you into the sky will come back in the same way as you saw him going into the sky."

12 Then they returned to Jerusalem from the mountain called Olivet, which is near Jerusalem, a Sabbath day`s journey away.

13 When they had come in, they went up into the upper chamber, where they were staying; that is Peter, John, James, Andrew, Philip, Thomas, Bartholomew, Matthew, James the son of Alphaeus, Simon the Zealot, and Judas the son of James.
