Revelation 1:5

The faithful witness,— In the original the nominative case is again used by St. John, contrary to the analogy of grammar, to signify, that, as he had intimated the immortality of the Deity, so likewise Christ was no less immutable in his kingdom and in his testimony. Christ is called the Prince of the kings of the earth, to encourage them in the profession of Christianity, notwithstandingthe opposition made by kings, whom he could easily defeat and destroy in a moment. See John 13:34; John 15:9. 1 John 1:7.
