Revelation 8:2

And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.

And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints upon the golden altar which was before the throne.

And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel's hand.

And the angel took the censer, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
