Revelation 8:1-4

When the Lamb broke the seventh seal, there was silence in heaven for about half an hour. And I saw the seven angels who stand before God, and seven trumpets were given to them. Another angel came and stood at the altar, holding a golden censer; and much incense was given to him, so that he might add it to the prayers of all the saints on the golden altar which was before the throne. And the smoke of the incense, with the prayers of the saints, went up before God out of the angel’s hand.
