Acts 1:7-9

New Revised Standard Version Catholic Edition

⁷ He replied, “It is not for you to know the times or periods that the Father has set by his own authority. ⁸ But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.” ⁹ When he had said this, as they were watching, he was lifted up, and a cloud took him out of their sight.
