Ma`asei (Acts) 1:10-11, 9

And as they were gazing into the heaven as He went up, see, two men stood by them dressed in white, who also said, “Men of Galil, why do you stand looking up into the heaven? This same יהושע, who was taken up from you into the heaven, shall come in the same way as you saw Him go into the heaven.”

And having said this, while they were looking on, He was taken up, and a cloud hid Him from their sight.
