The first letter in almost all alphabets. In Hebrew, it is called aleph, in Greek, alpha, the last letter in the Greek alphabet being omega. Both the Hebrews and Greeks used their letters as numerals; and hence A (aleph or alpha) denoted one, or the first. So our Lord says, "I am Alpha and Omega, the beginning and the end, the first and the last;" thus declaring his eternity and that he is the cause and end of all things, Re 1:8,11; 21:6; 22:13; Isa 44:6; 48:12; Col 1:15-18.
Alpha, the first letter of the Greek alphabet, as Omega is the last. These letters occur in the text of Re 1:8,11; 21:6; 22:13, and are represented by "Alpha" and "Omega" respectively (omitted in R.V., Re 1:11). They mean "the first and last." (Comp. Heb 12:2; Isa 41:4; 44:6; Re 1:11,17; 2:8.) In the symbols of the early Christian Church these two letters are frequently combined with the cross or with Christ's monogram to denote his divinity.
