'Cloud' in the Bible

And I saw another powerful angel descending from heaven, wrapped in a cloud, and a rainbow over his head, and his face [was] like the sun, and his feet [were] like pillars of fire,

And they heard a loud voice from heaven saying to them, "Come up here," and they went up into heaven in a cloud, and their enemies watched them.

And I looked, and behold, a white cloud, and on the cloud was seated [one] like a son of man, having on his head a golden crown, and in his hand a sharp sickle.

And another angel came out of the temple, crying out with a loud voice to the one seated on the cloud, "Send out your sickle and reap, because the hour to reap has come, because the harvest of the earth is ripe!"

And the one seated on the cloud swung his sickle on the earth, and the earth was reaped.
