Revelation 1:8

Alpha and Omega [τ ο α κ α ι τ ο ω]. Rev., rightly, gives the article, "the Alpha," etc. The words are explained by the gloss, properly omitted from the text, the beginning and the ending. The Rabbinical writers used the phrase from Aleph to Tav, to signify completely, from beginning to end. Thus one says, "Adam transgressed the whole law from Aleph even to Tav." Compare Isaiah 41:4; Isaiah 43:10; Isaiah 44:6.

The Lord [ο κ υ ρ ι ο ς]. See on Matthew 21:3. The best texts read Kuriov oJ Qeov the Lord the God. Rev., the Lord God.

Which is, etc. See on verse 4. "God, as the old tradition declares, holding in His hand the beginning, middle, and end of all that is" (Plato, "Laws," 715).

The Almighty [ο π α ν τ ο κ ρ α τ ω ρ]. Used only once outside of Revelation, in 2 Corinthians 6:18, where it is a quotation. Constantly in the Septuagint.
