Acts 1:9

6 So, when they were together, they said to him, Lord, will you at this time give back the kingdom to Israel?

7 And he said to them, It is not for you to have knowledge of the time and the order of events which the Father has kept in his control.

8 But you will have power, when the Holy Spirit has come on you; and you will be my witnesses in Jerusalem and all Judaea and Samaria, and to the ends of the earth.

9 And when he had said these things, while they were looking, he was taken up, and went from their view into a cloud.

10 And while they were looking up to heaven with great attention, two men came to them, in white clothing,

11 And said, O men of Galilee, why are you looking up into heaven? This Jesus, who was taken from you into heaven, will come again, in the same way as you saw him go into heaven.

12 Then they went back to Jerusalem from the mountain named Olivet, which is near Jerusalem, a Sabbath day's journey away.
