R. Shimon bar Aba quoting R. Yochanan: The Mishnah (see earlier 30-1)(f)) should read that the Lulav must be 3 Tefachim, and in addition, a space (of a Tefach) on top to shake.

Beraisa: The Hadas (myrtle) and the Aravah (willow branch) must be 3 Tefachim long and the Lulav must be four.

Beraisa: R. Tarfon says - The measurements are calculated using an Amah of five Tefachim.

Chachamim say - They are calculated using an Amah of six Tefachim (which makes each Tefach smaller).

According to R. Tarfon the Tefachim are large and according to Chachamim they are small.

R. Yona/ R"SBL quoting R. Yehuda HaNasi: The Lulav must be a Tefach taller than the Hadas and the Aravah.

R. Simon quoting R"YBL: The hyssop used for the purification of the Metzorah (leper) must be a Tefach.

Question (R. Zeira): Is R"YBL agreeing that a Lulav must be a Tefach and merely adding that a hyssop must also be a Tefach or is he disagreeing with R. Yona and holds that only a hyssop is a Tefach?

R. Yosi: The answer is clear, as R. Chinana say that R. Simon quoted R"YL as saying that a Lulav must be a Tefach; a hyssop must be a Tefach; a Shofar must be the length of a Tefach; a placenta (of a miscarriage) must be the length of a Tefach (for the house to be Tameh). Some add that the third wall of a Sukah may be a Tefach long.

Query (R. Zeira): Must the leaves of the Lulav extend a Tefach (aside from the spine)? Must the hyssop be a Tefach aside from the stem?

Answer (R. Yosa/ R. Tavi quoting Rav/ R. Chinana/ R. Parnach/ Rav Masnah/ Yosi bar Menasya quoting Rav): The leaves of a Lulav must extend a Tefach aside from the spine; a hyssop must be a Tefach aside from the stem.
