Revelation 14:15-17
14:15 Then another angel came out of the temple, shouting in a loud voice to the one seated on the cloud, “Use your sickle and start to reap, because the time to reap has come, since the earth’s harvest is ripe!”
14:16 So the one seated on the cloud swung his sickle over the earth, and the earth was reaped.
14:17 Then another angel came out of the temple in heaven, and he too had a sharp sickle.
