Why does the fact that something in extra (mefnah) tell us to learn semuchin?
Mark Cutler, Chicago, USA
The concept of Semuchin is learned from the Pasuk Semuchin la'Ad l'Olam. However we still need an indication that the two words were juxtaposed in order to teach us a new Limud, rather than mere logical sequence. When one is extra we see that the Torah placed it here for the explicit purpose of teaching us something.
