Acts 1:8-12

8But 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.”

9And after He said these things, He was caught up as they looked on, and a cloud took Him up out of their sight.

10While they were looking intently into the sky as He was going, two men in white clothing suddenly stood beside them,

11who 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.”

12Then 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.
