Acts 1:3-11

³to whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:

⁴and, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.

⁵For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.

⁶When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?

⁷And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.

⁸But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth.

⁹And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.

¹⁰And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;

¹¹which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
