'Prayers' in the Bible

And when he had taken the book, the four living creatures and the four and twenty elders fell down before the Lamb, having each one a harp, and golden bowls full of incense, which are the prayers of the saints.

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

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