Avi K -“1. You are correctt hat Rashi changes the girsa to “nogef”. However, I will wave mine and point out that one cannot bank one’s finger without moving it in some manner.”
Well thank you for Not arguing on Rashi. It’s a good thing because if YOU argued -then Rashi would have to retract.
And the point has nothing to do with moving only with pain to bring you to Teshuva and you get a Kappara.
