Alpha and Omega are the first and last letters in the Greek alphabet, as Aleph and Tau are in the Hebrew alphabet: the meaning of these is expounded, the beginning and the ending; he who was before all, and shall continue to exist when all creatures shall cease to be; the first and the last, as the same terms are expounded, Revelation 22:13: so Isaiah 41:4, Isaiah 43:13. Which is, and which was, and which is to come, the Almighty: see Revelation 1:4: He addeth the Almighty, to show that he was able to make his words good. Thus in this verse, omnipotency, eternity, and immutability, are all applied to God, and particularly predicated of our Lord and Saviour Jesus Christ.
