Of Hebrew origin; the first letter of the alphabet: figuratively only (from its use as a numeral) the first. Often used (usually {an} before a vowel) also in composition (as a contraction from G427) in the sense of privation; so in many words beginning with this letter; occasionally in the sense of union (as a contraction of G260): - Alpha.
Rev 1:11Saying, I am AlphaG1 and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
Rev 21:6And he said unto me, It is done. I am AlphaG1 and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
