Acts 1:7-11

“You don't need to know about the dates and times that are set by the Father's authority,” he told them.

“But you will be given power when the Holy Spirit comes upon you, and you will be my witnesses in Jerusalem, throughout Judea and Samaria, and to the farthest places on earth.”

After Jesus had told them this, he was taken up as they were watching and a cloud hid him from their sight.

While they were staring intently at the sky as he ascended, two men dressed in white were suddenly standing beside them.

“Men of Galilee, why are you standing here staring at the sky?” they asked. “This same Jesus who has been taken up from you to heaven shall come in the same way you saw him go into heaven.”
