Then He said to them, "Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem.  And you are witnesses of these things.  Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high." 

Luke 24:46-49   (NKJV)
