The "Aleph Bet" refers to the Hebrew alphabet, which consists of 22 letters. Each letter has its own unique sound and significance, and they are written from right to left. The first letter, Aleph, is often associated with the number one, while the last letter, Tav, represents the number 400. In addition to being used for writing, the Aleph Bet is also important in Jewish tradition and religious texts. Each letter can symbolize various concepts, and they are often used in Kabbalah to convey deeper spiritual meanings. The Aleph Bet serves as a foundation for the Hebrew language and culture.
