Acts 1:4 - 1:8
4 And gathering them together, He commanded them not to leave Jerusalem, but to wait for the promise of the Father, “Which,” He said, “you heard of from Me; 5 for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.” 6 So when they had come together, they were asking Him, saying, “Lord, is it at this time You are restoring the kingdom to Israel?” 7 But He said to them, “It is not for you to know times or seasons which the Father has set by His own authority; 8 but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the end of the earth.”
