Revelation 1:8

“I am Alpha and Omega, etc.] These are the words of Christ himself, appearing at once, and confirming what John had said of him, concerning his person, offices, and future coming: Alpha is the first letter, and Omega the last in the Greek alphabet, and signifies that Christ is the first and the last, as it is interpreted in (<660111>Revelation 1:11,17), and is a character often given to the divine Being in prophetic writings; (see <234104> Isaiah 41:4 44:6 48:12); and is no small proof of the proper deity of Christ. Alpha is used by the Jews for the chief of persons or things; “Macmas and Mezonicha (names of places) are tlsl apla, “Alpha for fine flour”;” that is, the best fine flour is…”

“Greek, "I am the Alpha and the Omega." The first and last letters of the alphabet. God in Christ comprises all that goes between, as well as the first and last. the beginning and the ending--omitted in the oldest manuscripts, though found in Vulgate and Coptic. Transcribers probably inserted the clause from Rev 21:6. In Christ, Genesis, the Alpha of the Old Testament, and Revelation, the Omega of the New Testament, meet together: the last book presenting to us man and God reconciled in Paradise, as the first book presented man at the beginning innocent and in God's favor in Paradise. Accomplishing finally what I begin. Always the same; before the dragon, the beast, false prophet, and all…”

“I am Alpha and Omega - These are the first and the last letters of the Greek alphabet, and denote properly the first and the last. So in Revelation 22:13, where the two expressions are united, “I am Alpha and Omega, the beginning and the end, the first and the last.” So in Revelation 1:17, the speaker says of himself, “I am the first and the last.” Among the Jewish rabbis it was common to use the first and the last letters of the Hebrew alphabet to denote the whole of anything, from beginning to end. Thus, it is said, “Adam transgressed the whole law, from ‘Aleph (א) to Taw (תּ).” “Abraham kept the whole law, from ‘Aleph (א) to Taw (תּ).” The language here is what would properly denote…”

“I am the Alpha and the Omega, saith the Lord God - Alpha is the first, Omega, the last, letter in the Greek alphabet. Let his enemies boast and rage ever so much in the intermediate time, yet the Lord God is both the Alpha, or beginning, and the Omega, or end, of all things. God is the beginning, as he is the Author and Creator of all things, and as he proposes, declares, and promises so great things: he is the end, as he brings all the things which are here revealed to a complete and glorious conclusion. Again, the beginning and end of a thing is in scripture styled the whole thing. Therefore God is the Alpha and the Omega, the beginning and the end; that is, one who is all things, and…”

“1:8 I am is the name of God in the Old Testament (Exod 3:13-14; 6:2; Deut 6:4). Jesus applied this name to himself (cp. John 4:26). Alpha and Omega are the first and last letters of the Greek alphabet; they signify that God’s actions are all-encompassing. God is fully in control.”

“Alpha: Rev 1:11, Rev 1:17, Rev 2:8, Rev 21:6, Rev 22:13; Isa 41:4, Isa 43:10, Isa 44:6, Isa 48:12 which is: Rev 1:4 the Almighty: Rev 4:8, Rev 11:17, Rev 16:14, Rev 19:15, Rev 21:22; Gen 17:1, Gen 28:3, Gen 35:11, Gen 43:14, Gen 48:3; Gen 49:25; Exo 6:3; Num 24:4; Isa 9:6; Co2 6:18 Revelation 1:9”
