Acts 1:6-12

So when they had come together, they asked Him repeatedly, “Lord, are You at this time reestablishing the kingdom and restoring it to Israel?” He said to them, “It is not for you to know the times or epochs which the Father has fixed by His own authority. But you will receive power and ability when the Holy Spirit comes upon you; and you will be My witnesses [to tell people about Me] both in Jerusalem and in all Judea, and Samaria, and even to the ends of the earth.” And after He said these things, He was caught up as they looked on, and a cloud took Him up out of their sight. While they were looking intently into the sky as He was going, two men in white clothing suddenly stood beside them, who said, “Men of Galilee, why do you stand looking into the sky? This [same] Jesus, who has been taken up from you into heaven, will return in just the same way as you have watched Him go into heaven.” Then the disciples returned to Jerusalem from the mount called Olivet (Olive Grove), which is near Jerusalem, [only] a Sabbath day’s journey (less than one mile) away.
