Thematic Bible: A son of man with a sickle

Then I looked, and behold, a white cloud, and seated on the cloud was one like a son of man, with a golden crown on his head, and a sharp sickle in his hand. And another angel came out of the temple, crying out with a loud voice to him who sat on the cloud, "Put in your sickle and reap, for the hour to reap has come, because the harvest of the earth is ripe." So he who sat on the cloud swung his sickle over the earth, and the earth was reaped.
