Acts 1:3-6

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?
