The picture below illustrates the Hebrew alphabet, in Hebrew alphabetical order. Note that Hebrew is written from right to left, rather than left to right as in English, so Alef is the first letter of the Hebrew alphabet and Tav is the last. The Hebrew alphabet is often called the "alefbet," because of its first two letters.
Letters of the Alefbet Table 1: The Hebrew Alphabet. Shabbat. For six days you may perform melachah, but the seventh day is a complete Sabbath, holy to the L-RD ... it is an eternal sign that in six days, the L-RD made heaven and earth, and on the seventh day he rested and was refreshed.
-Exodus 31:15-17 The Nature of Shabbat The Sabbath (or Shabbat, as it is called in Hebrew) is one of the best known and least understood of all Jewish observances. People who do not observe Shabbat think of it as a day filled with stifling restrictions, or as a day of prayer like the Christian Sabbath.
