[Acts 1:4-8]

4 On one occasion, while he was eating with them, he gave them this command: "Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about.
5 For John baptized with water, but in a few days you will be baptized with the Holy Spirit."
6 So when they met together, they asked him, "Lord, are you at this time going to restore the kingdom to Israel?"
7 He said to them: "It is not for you to know the times or dates the Father has set by his own authority.
8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
