Acts 1:6-11

Therefore, those who had assembled together questioned him, saying, "Lord, is this the time when you will restore the kingdom of Israel?" But he said to them: "It is not yours to know the times or the moments, which the Father has set by his own authority. But you shall receive the power of the Holy Spirit, passing over you, and you shall be witnesses for me in Jerusalem, and in all Judea and Samaria, and even to the ends of the earth." And when he had said these things, while they were watching, he was lifted up, and a cloud took him from their sight. And while they were watching him going up to heaven, behold, two men stood near them in white vestments. And they said: "Men of Galilee, why do you stand here looking up toward heaven? This Jesus, who has been taken up from you into heaven, shall return in just the same way that you have seen him going up to heaven."
