The
Ketzos HaChoshen (;
Ashkenazi Hebrew ) is a major writing by Aryeh Leib Heller (1745–1812)
and the origin of his nickname, "the Ketzos". Its first printing was in
Lviv.
Importance
The
Ketzos HaChoshen is a
halakhic work that explains difficult passages in the
Shulchan Aruch,
Choshen Mishpat (which deals mainly with business and financial laws such as contracts, witnesses, etc.) with novel ideas proposed by Aryeh Leib.
[Ex. ] Familiarity with this work is considered mandatory for any
Torah scholar or Dayan. It is customarily studied in conjunction with the
Nesivos HaMishpat of Yaakov Lorberbaum,
[who is therefore known as The "Ba'al HaNesivos."] who often controverted Heller's conclusions on many points.
The Ketzos's sefer is often published in tandem with his brother Yehuda Heller Kahana's book, Kuntras HaSfeikos, as a two-volume set.
