Acts 1:4-8 - The Holy Spirit Promised
4 And, being collected together, he enjoined them not to be separated from Jerusalem, but to wait for the solemn promise of the Father, which ye heard of me. 5 For John truly immersed in water; and ye shall be immersed in the Holy Spirit not after these many days.
6 Truly they therefore having come together, asked him, saying, Lord, if in this time thou wilt restore the kingdom of Israel?
7 And he said to them, It is not yours to know the times and occasions, which the Father fixed in his own power. 8 But ye shall receive power, the Holy Spirit having come upon you: and ye shall be witnesses to me also in Jerusalem, and in all Judea, and Samaria, and even to the last of the earth.
