Pshat: Lifnei Iver Means Bad Advice
- The simple pshat of lifnei iver (Lo siten mechshol) focuses on giving harmful advice to someone 'blind' in that area.
- The Kliyakor reads the full pasuk to show it targets hidden-intent cases, not obvious physical traps.
Major Rishonim Split On Facilitating Murder
- There's a major Rishonim dispute whether lifnei iver that facilitates murder requires giving one's life (yehareh v'al ya'avor).
- The Rambam/Ramban split reflects whether facilitating is treated as the core sin or a secondary, supportive act.
Does Attempted Persuasion Count?
- Gemara sources conflict on whether unsuccessful attempts to cause sin still violate lifnei iver.
- One sugya treats the attempt itself as actionable while another focuses on the actual resulting harm.
