Acts 1:8-9

8But the Holy Spirit will come to you, and he will give you power. The Holy Spirit will make your spirit strong. Then you will tell other people everywhere in the world about me. You will do that in Jerusalem, in Judea, in Samaria and in places far away.’

9When Jesus had finished speaking to his apostles, God took him up to heaven. The apostles watched Jesus while he went up. Then a cloud hid him and they could not see him any more.
