Sanhedrin 48: Kingly vs. Courtly Executions

A dispute between Abaye and Rava whether designating an item - in this case, a shroud - is sufficient to prohibit it from common use, or whether that designating is not enough to do so (Abaye prohibits; Rava permits). Plus, examples (pro and con), though in the end, the halakhah follows Rava. Also, with regard to a condemned person, the Gemara addresses the differences between a king's execution vs. when such an event is overseen by the court. With examples from the Bible - eg: King Achav and Navot, plus others.
