(重定向自Shach)

Shabbatai ben Meir HaKohen (Hebrew:שבתי כהן; 1621–1662) was a noted 17th Century talmudist and halakhist. He became known as the Shakh, (Hebrew:ש"ך) which is an abbreviation of his most important work, Siftei Kohen (Hebrew:שפתי כהן) (literally Lips of the Priest), and his rulings were considered authoritative by later halakhists.
