Acts 1:6-11
6So when they had come together, they were asking Him, saying, “Lord, is it at this time You are restoring the kingdom to Israel?” 7He said to them, “It is not for you to know times or epochs which the Father has fixed by His own authority; 8but 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 remotest part of the earth.”
9And after He had said these things, He was lifted up while they were looking on, and a cloud received Him out of their sight. 10And as they were gazing intently into the sky while He was going, behold, two men in white clothing stood beside them. 11They also said, “Men of Galilee, why do you stand looking into the sky? This Jesus, who has been taken up from you into heaven, will come in just the same way as you have watched Him go into heaven.”
