Revelation 14:18

Revelation 15:5-8

15:5 After these things I looked, and the temple (the tent of the testimony) was opened in heaven, 15:6 and the seven angels who had the seven plagues came out of the temple, dressed in clean bright linen, wearing wide golden belts around their chests. 15:7 Then one of the four living creatures gave the seven angels seven golden bowls filled with the wrath of God who lives forever and ever, 15:8 and the temple was filled with smoke from God’s glory and from his power. Thus no one could enter the temple until the seven plagues from the seven angels were completed.
