[Act 1:3-5 KJV]

3 To 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:

4 And, 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.

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