Revelation 14:17
Revelation 14:1717Then another angel came out of the temple in heaven, and he too had a sharp sickle.
Watchtower commentary takes as a parallel scene to v15 — another angel emerges from the heavenly sanctuary, this time wielding the sickle that gathers the vine of the earth for the great winepress of God's wrath. The emphasis falls on the executive judgment of the wicked, with the heavenly sanctuary as the authoritative source.
Note the explicit phrase: "the temple sanctuary that is in heaven." The verse hands you the location of every other Revelation naos use without ambiguity. Naos consistently refers to the heavenly inner sanctuary throughout the book — 4:2-11, 7:15, 11:19, 14:15, 14:17, 15:5-8, 16:1, 16:17. So when says the great crowd "renders sacred service day and night in his temple," it means the heavenly sanctuary too. The Watchtower would need to explain why naos means "heaven" in every other verse and suddenly means "earth" in 7:15. The verse here removes any ambiguity about where Revelation's temple is.
