Acts 1:6-8 NIV

[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.”
