The bowls are the saints' prayers brought to God by the angelic elders (cf. Rev. 8:3-4), whereas the incense is Christ added to the saints' prayers. See note Rev. 8:34d. That in their worship to God the twenty-four angelic elders are holding the golden bowls full of incense shows that they, as priests, are ministering to God by bringing the saints' prayers to Him.
