Revelation 14:15-17

15Then another angel came out of the temple, crying out in a loud voice to the One seated on the cloud, “Swing Your sickle and reap, because the time has come to harvest, for the crop of the earth is ripe.” 16So the One seated on the cloud swung His sickle over the earth, and the earth was harvested.

17Then another angel came out of the temple in heaven, and he too had a sharp sickle.
