Luke 24:50-53 - The Ascension
6 So those who were present began to ask Him, "Lord, is this the time when you are going to set up the kingdom again for Israel?"
7 He answered them, "It is not your business to learn times and dates which the Father has a right to fix, 8 but you are going to receive power when the Holy Spirit comes upon you, and you must be witnesses for me in Jerusalem and all over Judea and Samaria, and to the very ends of the earth."
9 After saying this, He was taken up while they were looking at Him, and a cloud swept under Him and carried Him out of their sight. 10 And while they were gazing after Him into heaven, two men dressed in white suddenly stood beside them, 11 and said to them, "Men of Galilee, why do you stand looking up into heaven? This very Jesus who has been taken up from you into heaven will come back in just the way you have seen Him go up into heaven."
