Edit William H. Sanford and Chuck Missler spread the idea that behind the Hebrew Aleph-Tav symbol there is a reference to Jesus. The combination Aleph-Tav includes Y’shua haMashiach (Jesus the Messiah). They come to this conclusion because Jesus says in Revelation 1: 8 that he is the alpha and the omega (the first and last letters in the Greek alphabet). In Revelation 21: 6 this is also combined with the statement that he is the beginning and the end. In the Hebrew alphabet, the aleph and the tav are the first and last letters.
Behind this interpretation stands a kabbalistic interpretation of the Bible. Kabbalah is searching for secret messages behind the written text. It is a search for something that the text does not say. But the focus should be on the content of the text.
