These are the first and last letters of the Greek alphabet. This phrase can be generalized to mean the beginning and the end of anything.
There are 24 letters in the Greek alphabet. There are 26 letters in our English alphabet. Our English X is the 24th letter, and this seems fitting. To X out means to close or end.
Why did we add the Y and Z to our English alphabet is a question I now have. Could this be a tribute to our incessant human need to ask why(Y) and our human need to sleep (Z) at the end of our days.
It is interesting to note that when you add up all the letters of “Alpha and Omega” and all the letters of “The beginning and the end”, you will find that they are equal. I did this and arrived at 17. You could take this one step further and arrive at 8. However, I am inclined to stop adding up the numbers when I am left with a 1 in front (or to the left.)
My conclusion after all of this is that numbers are the universal language and all our letters have been ordered to follow suit.
I’m reminded of a dream I had in the beginning of my number obsession. I woke up from a nap saying aloud: “I am one, I am 1, I am 1.”
The word “one” adds up to 34, and this adds up to 7.
