Acts 1:2

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

2 until the day in which he was received up, after that he had given commandment through the Holy Spirit unto the apostles whom he had chosen:

3 To whom he also showed himself alive after his passion by many proofs, appearing unto them by the space of forty days, and speaking the things concerning the kingdom of God:

4 and, being assembled together with them, he charged them not to depart from Jerusalem, but to wait for the promise of the Father, which, [said he], ye heard from me:

5 For John indeed baptized with water; but ye shall be baptized in the Holy Spirit not many days hence.

6 They therefore, when they were come together, asked him, saying, Lord, dost thou at this time restore the kingdom to Israel?

7 And he said unto them, It is not for you to know times or seasons, which the Father hath set within His own authority.
