Acts 1:5-8 New International Version (NIV)

5 For John baptized with[a] water, but in a few days you will be baptized with[b] the Holy Spirit.”

6 Then they gathered around him and 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.”
