Acts 1:7-9

Revised Standard Version Catholic Edition

⁷ He said to them, “It is not for you to know times or seasons which the Father has fixed by his own authority. ⁸ But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samar′ia and to the end of the earth.” ⁹ And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight.
