Incense: Symbolical of the Prayers of Saints

When He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp, and they were holding golden bowls full of incense, which are the prayers of the saints.

Then another angel, who had a golden censer, came and stood at the altar. He was given much incense to offer, along with the prayers of all the saints, on the golden altar before the throne.

And the smoke of the incense, together with the prayers of the saints, rose up before God from the hand of the angel.
