Revelation 14:14-17

14Again I looked, and this is what I saw: a white cloud, and sitting on the cloud was One like the Son of Man, with a crown of gold on His head and a sharp sickle [of swift judgment] in His hand.

15And another angel came out of the temple, calling with a loud voice to Him who was sitting upon the cloud, “Put in Your sickle and reap [at once], for the hour to reap [in judgment] has arrived, because the earth’s harvest is fully ripened.”

16So He who was sitting on the cloud cast His sickle over the earth, and the earth was reaped (judged).

17Then another angel came out of the temple (sanctuary) in heaven, and he also had a sharp sickle.
