Acts 1:1-3

1 The first book I wrote, Theophilus, concerned all that Yeshua 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 emissaries 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.
