And here I was, thinking you only cared about what the Bible says.
According to EncycloBritan:
Halakhah, (Hebrew: “the Way”) also spelled Halakha, Halakah, or Halachah, plural Halakhahs, Halakhot, Halakhoth, or Halachot, in Judaism, the totality of laws and ordinances that have evolved since biblical times to regulate religious observances and the daily life and conduct of the Jewish people. Quite distinct from the Law, or the Pentateuch (the first five books of the Bible), Halakhah purports to preserve and represent oral traditions stemming from the revelation on Mount Sinai or evolved on the basis of it. The legalistic nature of Halakhah also sets it apart from those parts of rabbinic, or Talmudic, literature that include history, fables, and ethical teachings (Haggada).
