Rev 15:5-8

After these things I saw, and the temple of the tabernacle of the testimony in heaven was opened. (Rev 15:5)

And out of the temple came the seven angels having the seven plagues, who were dressed in pure bright linen, and having their chests girded with golden belts. (Rev 15:6)

Then one of the four living beings gave to the seven angels seven golden bowls full of the wrath of God who lives forever and ever. (Rev 15:7)

And the temple was filled by the smoke from the glory of God and from His power, and no one was able to enter into the temple until the seven plagues of the seven angels were finished. (Rev 15:8)
