In the first book, O 1Theophilus, I have dealt with all that Jesus began 2to do and teach,
until the day when 3he was taken up, after he 4had given commands 5through the Holy Spirit to the apostles whom he had chosen.
6He presented himself alive to them after his suffering by many proofs, appearing to them during forty days and speaking about the kingdom of God.
And while staying with them 7he ordered them not to depart from Jerusalem, but to wait for the promise of the Father, which, he said, "you heard from me;
for 8John baptized with water, 9but you will be baptized 10with the Holy Spirit not many days from now."
