The Book of Revelation: Chapter 14

The visions of John the Apostle brought him back to the heavenly throne room, in which he saw again the 144,000 Israelites who were sealed by the seal of God. Angels joined them in one last global campaign to compel the world to repent and to warn the world of the wrath of the Lord against those who pledged their worship and loyalty to the anti-Christ. A harvest happenned, and the angels partook with the Lamb in it.
