15 Another angel came out from the temple, crying with a loud voice to him who sat on the cloud, “Send forth your sickle, and reap; for the hour to reap has come; for the harvest of the earth is ripe!”
another angel came out of the temple – that is out of the end time Sanctified Church, which is described as the temple, as opposed to “the tabernacle” of the saints in the wilderness. John will describe the cleansing of the lawless by the end time Church.
the hour to reap has come – this is the last of the twelve “hours” of man’s existence described in Revelation. The 9th hour was in Rev 17:12; the 10th at Rev 11:13; and the 11th at Rev 14:7.
the harvest of the earth is ripe – the Angels are those described in Matt 13:36-39, gathering the wheat with the tares. But here in Revelation we actually use the metaphor of grapes, we find in Isa 63:1-6, and Rev 19:15: “he treads the wine press of the fierce wrath of God, the Almighty.”
This is the end of the cleansing of the sanctuary, the cleansing of the kingdom of heaven, that Daniel prophesied would take 2,300 days.
