Acts 1:4-8 - The Holy Spirit Promised
4 and assembling them together, commanded them not to depart from Jerusalem, but to wait for the promise of the Father, which, said he, ye have heard from me. 5 For John indeed baptised with water; but ye shall be baptised with the Holy Ghost not many days after the present.
6 They then accordingly assembling together, asked him, saying, Lord, wilt thou at this time reestablish the kingdom of Israel?
7 But he said unto them, It is not for you to know the times and the seasons, which the Father hath reserved under his own authority. 8 But ye shall receive power, when the Holy Ghost is come upon you: and ye shall be witnesses for me, both in Jerusalem, and throughout all Judea, and Samaria, and unto the extremity of the earth.
