Rev. 1:8 “I am the Alpha and the

Rev. 21:6 “And He said to me, “It is done. I am the Alpha and the Omega, the beginning and the end. I will give to the one who thirsts from the spring of the water of life without cost.”
Rev. 22:13 “I am the Alpha and the Omega, the first and the last, the beginning and the end.”
“Alpha” was the first letter of the Greek alphabet (in fact we see that word “alpha” in “alphabet”) and “omega” was the last letter of the Greek alphabet. Jesus is the “A” and “Z,” or the “beginning and the end.” In fact, these very words are used in Rev. 22:13.
