Revelation them. 8.3 Another angel came and stood over the altar, having a golden censer. Much incense was given to him, that he should add it to the prayers of all the saints on the golden altar which was before the throne. 8.4 The smoke of the incense, with the prayers of the saints, went up before God out of the angels hand. 8.5 The angel took the censer, and he filled it with the fire of the altar, and threw it on the earth. There followed thunders, sounds, lightnings, and an earthquake. - WEB Bible.
