Revelation 1:3

he that readeth, and they that hear—namely, the public reader in Church assemblies, and his hearers. In the first instance, he by whom John sent the book from Patmos to the seven churches, read it publicly: a usage most scriptural and profitable. A special blessing attends him who reads or hears the apocalyptic "prophecy" with a view to keeping the things therein (as there is but one article to "they that hear and keep those things," not two classes, but only one is meant: "they who not only hear, but also keep those things," Romans 2:13); even though he find not the key to its interpretation, he finds a stimulus to faith, hope, and patient waiting for Christ. Note: the term "prophecy" has relation to the human medium or prophet inspired, here John: "Revelation" to the Divine Being who reveals His will, here Jesus Christ. God gave the revelation to Jesus: He by His angel revealed it to John, who was to make it known to the Church.
