Revelation 8:2-4

2And I saw the seven angels who stand before God, and to them were given seven trumpets.

3Then another angel, having a golden censer, came and stood at the altar. He was given much incense, that he should offer it with the prayers of all the saints upon the golden altar which was before the throne.

4And the smoke of the incense, with the prayers of the saints, ascended before God from the angel’s hand.
