Acts 1:2

1The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach,

2Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:

3To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:

4And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.
