Acts 1:1-3 TMB

1 In the former treatise, O Theophilus, I have given an account of all that Jesus began both to do and teach
2 until the day in which He was taken up, after He had given commandments through the Holy Ghost unto the apostles, whom He had chosen.
3 To these also He showed Himself alive after His passion by many infallible proofs, being seen by them forty days, and speaking of the things pertaining to the Kingdom of God.
