This week, after the culmination of the High Holy Days of the Bible, the cycle of Parsha reading is once again reset at the beginning of the Torah, Genesis 1:1 to 6:8. According to Wikipedia~ A parashah (Hebrew: פָּרָשָׁה Pārāšâ "portion," plural: parashot or parashiyot) formally means a section of a biblical book in the Masoretic Text1 of the Tanakh (Hebrew Bible). In the Masoretic Text, parashah sections are designated by various types of spacing between them, as found in Torah scrolls, scrolls of the books of Nevi'im or Ketuvim (especially megillot), masoretic codices from the Middle Ages and printed editions of the masoretic text.
The division of parashot found in the modern-day Torah scrolls of all Jewish communities is based upon the systematic list provided by Maimonides in Mishneh Torah, Laws of Tefillin, Mezuzah and Torah Scrolls. Maimonides based his division of the parashot for the Torah on the Aleppo Codex. The division of parashot for the books of Nevi'im and Ketuvim was never completely standardized in printed Hebrew bibles and handwritten scrolls.
In fact, according to the Law, almost everything is purified with blood; indeed, without the shedding of blood there is no forgiveness of sins.
