Revelation 5:8 When He had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one holding a harp and golden bowls full of incense, which are the prayers of the saints.

Revelation 8:3 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.

Revelation 8:4 And the smoke of the incense, with the prayers of the saints, went up before God out of the angel's hand. (NASB ©1995)
