Wine Libated to Idols: Laws and Prohibitions
Yayin nesech—wine libated to or dedicated for idolatrous worship—is completely prohibited for benefit or consumption according to Jewish law. The sources trace the biblical foundation of wine-related prohibitions, the rabbinic development of distinctions between yayin nesech and stam yeinam (ordinary wine handled by non-Jews), and the practical halakhic rulings that govern contact, handling, and use of such wine.

Was Pinchas Acting as a Rodef?
The sources examine whether Pinchas's killing of Zimri and Kozbi constitutes an act of zealotry (kana'im pog'in bo) or falls under the legal category of a rodef (pursuer).

Rishonim on the Urim and Tumim's Spiritual Function
Medieval and classical Jewish sources explore how the Urim and Tumim functioned as a divinely sanctioned oracular instrument for priestly decision-making.

The sources range from Tanakh narratives of zealous religious violence to Talmudic rulings and Maimonidean codification of their exclusion from communal life and the World to Come.
