Thematic Bible: When you will receive power

Therefore indeed having assembled, they asked Him saying, Lord, do you at this time restore the kingdom to Israel? He said to them; It is not your province, to know the times or seasons, which the Father placed in His own authority. But you shall receive the power of the Holy Ghost having come upon you, and shall be my witnesses both in Jerusalem, and all Judea, and in Samaria, and into the extremity of the earth.
