Acts 1:6-11

6They therefore, when they were come together, asked him, saying, Lord, dost thou at this time restore the kingdom to Israel? 7And he said unto them, It is not for you to know times or seasons, which the Father hath set within his own authority. 8But ye shall receive power, when the Holy Spirit is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea and Samaria, and unto the uttermost part of the earth. 9And when he had said these things, as they were looking, he was taken up; and a cloud received him out of their sight. 10And while they were looking steadfastly into heaven as he went, behold two men stood by them in white apparel; 11who also said, Ye men of Galilee, why stand ye gazing into heaven? this Jesus, who was received up from you into heaven, shall so come in like manner as ye beheld him going into heaven.
