Acts 1:1-5 - The Preface
1 THE former treatise, Theophilus, I composed, concerning all things which Jesus began both to do and to teach, 2 until that day, when having given a charge to his apostles through the Holy Ghost, whom he had chosen, he was taken up: 3 to whom also he had shewed himself alive, after he had suffered, by many infallible proofs, during forty days being frequently seen by them, and speaking of the things which relate to the kingdom of God:
4 and assembling them together, commanded them not to depart from Jerusalem, but to wait for the promise of the Father, which, said he, ye have heard from me. 5 For John indeed baptised with water; but ye shall be baptised with the Holy Ghost not many days after the present.
