Being assembled together with them, he charged them, "Don't depart from Jerusalem, but wait for the promise of the Father, which you heard from me. For John indeed baptized in water, but you will be baptized in the Holy Spirit not many days from now." Therefore, when they had come together, they asked him, "Lord, are you now restoring the kingdom to Israel?" He said to them, "It isn't for you to know times or seasons which the Father has set within His own authority. But you will receive power when the Holy Spirit has come upon you. You will be witnesses to me in Jerusalem, in all Judea and Samaria, and to the uttermost parts of the earth."
