Law given to Moses at Sinai

A law given to Moses at Sinai (Hebrew: הלכה למשה מסיני, romanized: Halakhah le-Moshe mi-Sinai) refers to a halakhic law for which there is no biblical reference or source, but rather was passed down orally as a teaching originating from Moses at Sinai. Such teachings have not been derived from any Talmudical hermeneutics, but known solely from the Jewish tradition.^[1]
