Revelation 8:1-4

And when he opened the seventh seal, there followed a silence in heaven about the space of half an hour. And I saw the seven angels that stand before God; and there were given unto them seven trumpets. And another angel came and stood over the altar, having a golden censer; and there was given unto him much incense, that he should add it unto the prayers of all the saints upon 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.
