Each week in synagogue, we read (or, more accurately, chant, because it is sung) a passage from the Torah. This passage is referred to as a parshah. The first parshah, for example, is Parashat Bereishit, which covers from the beginning of Genesis to the story of Noah. There are 54 parshahs, one for each week of a leap year, so that in the course of a year, we read the entire Torah (Genesis to Deuteronomy) in our services. During non-leap years, there are 50 weeks, so some of the shorter portions are doubled up. We reach the last portion of the Torah around a holiday called Simkhat Torah (Rejoicing in the Law), which occurs in October, a few weeks after Rosh Hashanah (Jewish New Year). On Simkhat Torah, we read the last portion of the Torah, and proceed immediately to the first paragraph of Genesis, showing that the Torah is a circle, and never ends.
