Alpha and Omega are the first and last letters of the Greek alphabet and a Divine Title for the Lord Jesus Christ in Revelation 22:13 signifying Him as the “eternal one,” the beginning and the end of all that exists.
The title also signifies Christ’s place in history as both first and last (John 1:1; Revelation 1:8; 21:6).
Please note: Koiné (koy-nay) Greek was the common language of the Jews when Christ walked among us.
