Acts 1:1-3

The Preface

1 I produced the former account, O Theophilus, about all {that}a Jesus began to do and to teach,
2 until the day he was taken up, [after he]b had given orders through the Holy Spirit to the apostles whom he had chosen,
3 to whom he also presented himself alive after he suffered, with many convincing proofs, appearing to them over a period of forty days and speaking the things about the kingdom of God.
