Acts 1:1-3 RSV

1 In the first book, O The-oph'ilus, I have dealt with all that Jesus began to do and teach,
2 until the day when he was taken up, after he had given commandment through the Holy Spirit to the apostles whom he had chosen.
3 To them he presented himself alive after his passion by many proofs, appearing to them during forty days, and speaking of the kingdom of God.
