Acts 1:10-12

10 They still had their eyes fixed on the sky as he went away, when two men dressed in white suddenly stood beside them

11 and said, "Galileans, why are you standing there looking up at the sky? This Jesus, who was taken from you into heaven, will come back in the same way that you saw him go to heaven."

12 Then the apostles went back to Jerusalem from the Mount of Olives, which is about half a mile away from the city.
