Matthew Poole and continuators on Revelation 1:8

8 I am Alpha, and Omega, the beginning and the ending, saith the Lord , which is, and which was, and which is to come, the Almighty .

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 End. 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, chap. 22.13. so Isa. 41.4. and 43.10.

See v. 4. He addeth the Almighty, to shew that he was able to make his words good. Thus in this Verse, Omnipoteny, Eternity, and Immutability, are all applied to God, and particularly predicated of our Lord and Savio[illegible: 2 letters] Jesus Christ.

Marginal references: Isa. 44.6. & 48.12. Chap, 21.6. & 23.13.; Ver. 4. Chap. 4.8. & 11.17. & 16.5.
