Acts of the Apostles 1:7-9 NLT
He replied, “The Father alone has the authority to set those dates and times, and they are not for you to know. But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere—in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”
After saying this, he was taken up into a cloud while they were watching, and they could no longer see him.
