Thanks to Kenny for this one. It’s from Megilah 15:
(b) (Beraisa): Rachav incited with her name, Ya’el with her voice, Avigayil with her mention, Michal Bas Shaul with her seeing.
1. (R. Yitzchak): Anyone who says “Rachav, Rachav” will immediately have an emission.
2. (Rav Nachman): I can say it and it won’t affect me.
3. (R. Yitzchak): I was referring to those that know and recognize her.
