"I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty." Jesus
Alpha (Α or α) and Omega (Ω or ω) are the first and last letters of the Greek alphabet, and a title of Christ or of God in the Book of Revelation 1:8.
That would be the same as A and Z in english.
Christ
α&ω Α&Ω A&O ש&א

When this letter appears as כ without the dagesh

Greek Chi/Ch 600 X
Chess = ושח
