Acts 1:1-3

NHEB^{(i) 1} The first account 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.
