The Four Species: waved but never shaken

The נענועים are an integral part of the mitzva of lulav (see Mesechte Sukkah 37b). But how is that waving supposed to be done? As anyone who’s ever been in a shul over Sukkos knows, the question seems to inspire a wide range of answers. The gemara’s conceptual source is the waving associated with the מלואים (see שמות כט:כז). There, the הנפה and הרמה referenced by the verse suggest to ר’ יוחנן that we should move the four species outwards and inwards, and then up and down.

One popular interpretation involves shaking the lulav with each movement. The source for this seems to be the Rema (תרנא:ט) who wrote:

ומכסכס הלולב בכל נענוע

The popular translation of כסכס is “shake.” However, from the Yerushalmi to Sukkah (פרק ג הלכה ח) this would not seem to be correct:

תני צריך לנענע ג’ פעמים ר’ זעירה בעי הכין חד והכין חד או הכין והכין חד או הכין הכין חד

One must wave (the lulav) three times. Rabbi Zeira asks: this way is one and this way is one, or this way and this way is one? (i.e., are those three waves made up of three sets of “in and out” movements, or one inward movement, one outward, and a third inward).

The Yerushalmi answers via a proof from the laws of Niddah (found in the Bavli in Niddah 62a). There, the required steps for properly cleaning a stain involves כסכוס three times in each direction. Here’s how the Yerushalmi concludes:

תמן תנינן צריך לכסכס ג’ פעמים בין כל דבר ודבר ר’ זעירה בעי הכין חד והכין חד

Which would seem to clearly limit the Rema’s ומכסכס to simple outward/inward/upward/downward movements. And there seems to be no source for shaking.

Just sayin’.

You’re probably familiar with the mishna in the third perek of Eiruvin:

…אם בא חכם מן המזרח עירובי למזרח בא מן המערב עירובי למערב

(A person may make an eruv techum – extending the distance he may travel outside his town on Shabbos – conditional, saying:) “If a wise man will come from the east, my eruv will (extend my techum) in the east (so I can go to meet him). If the wise man will come from the west, my eruv will be in the west.”

But you may not be aware of an alternate reading quoted in the Yerushalmi (עירובין פרק ו הלכה ג):

אית תניי תני במערב מאן דמר במזרח באילין חכימי’ מאן דמר במערב ברגיל

“There is a tana who taught: ‘(regarding the wise man who comes from the east, that he wants his eruv in the) west. The one who would say (his eruv should be in) the east refers a to (true) wise man. The one who says (his eruv should be in) the west refers to a wise man (who only teaches things everybody already knows).

The scenario presented by the alternate version gives us a man whose motivation for setting an eruv techum is to escape from the chochom, presumably so he wouldn’t need to sit through his lecture.

But this gets more interesting. Later in Eiruvin (פרק ח הלכה א), we find that one should only set an eruv techum for the purpose of a mitzva. Meaning that, according to the Yerushalmi’s version, not only is it reasonable for a person to wish to escape a chochom, but it can even be a mitzva!
