Doctrine and Covenants 128:20

And again, what do we hear? Glad tidings from Cumorah! ^a Moroni, ^b an angel from heaven, declaring the fulfilment of the prophets—the book ^c to be revealed. A voice of the Lord in the wilderness of Fayette, Seneca county, declaring the three witnesses to bear record ^d of the book! The voice of Michael ^e on the banks of the Susquehanna, detecting the devil ^f when he appeared as an angel of light! ^g The voice of Peter, ^h James, and John in the wilderness between Harmony, Susquehanna county, and Colesville, Broome county, on the Susquehanna river, declaring themselves as possessing the keys ⁱ of the kingdom, and of the dispensation of the fulness of times!
