Acts 1:4-9

4and, being assembled with [them], commanded them not to depart from Jerusalem, but to await the promise of the Father, which [said he] ye have heard of me.

5For John indeed baptised with water, but ye shall be baptised with the Holy Spirit after now not many days.

6They therefore, being come together, asked him saying, Lord, is it at this time that thou restorest the kingdom to Israel?

7And he said to them, It is not yours to know times or seasons, which the Father has placed in his own authority;

8but ye will receive power, the Holy Spirit having come upon you, and ye shall be my witnesses both in Jerusalem, and in all Judaea and Samaria, and to the end of the earth.

9And having said these things he was taken up, they beholding [him], and a cloud received him out of their sight.
