Acts 1:1-5 - The Preface

¹ The first book I wrote, Theophilus, concerned all that Jesus began both to do and to teach, ² until the day in which he was received up, after he had given commandment through the Holy Spirit to the apostles whom he had chosen. ³ To these he also showed himself alive after he suffered, by many proofs, appearing to them over a period of forty days, and speaking about God's Kingdom.

⁴ Being assembled together with them, he commanded them, "Don't depart from Jerusalem, but wait for the promise of the Father, which you heard from me. ⁵ For John indeed baptized in water, but you will be baptized in the Holy Spirit not many days from now."
