Acts 1:9

7He said to them, “It isn’t for you to know times or seasons which the Father has set within his own authority.

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

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

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

11who 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.”
