Acts 1:1-3
Acts 1: 1 to 3
1 The former account, indeed, I made concerning all things, O Theophilus, that Jesus began both to do and to teach,
2 till the day in which, having given command, through the Holy Spirit, to the apostles whom he did choose out, he was taken up,
3 to whom also he did present himself alive after his suffering, in many certain proofs, through forty days being seen by them, and speaking the things concerning the reign of God.
