Acts 1:7-8

King James Version

⁷ And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.

⁸ But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
