Acts 1:7-9

Amplified Bible

⁷ He said to them, “It is not for you to know the times or epochs which the Father has fixed by His own authority. ⁸ 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.”

The Ascension

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