And others raise it as a contradiction. We learned in the mishna: A lulav from the palms of the Iron Mountain is fit. But isn’t it taught in a baraita: It is unfit? Abaye said: This is not difficult: Here, in the mishna, where the lulav is fit, it is referring to a case where the top of this leaf reaches the base of that next leaf, whereas, there, in the baraita, where the lulav is unfit, it is referring to a case where the top of this leaf does not reach the base of that next leaf.

The Gemara describes the location of these lulavim. Rabbi Maryon said that Rabbi Yehoshua ben Levi said, and some say that Rabba bar Mari taught this baraita in the name of Rabban Yoḥanan ben Zakkai: There are two date palms in the valley of ben Hinnom, and smoke arises from between them. And this is the place about which we learned in the mishna: A lulav from the palms of the Iron Mountain is fit. And that site is the entrance of Gehenna.

The mishna continues: A lulav that has three handbreadths in length, sufficient to enable one to wave with it, is fit for use in fulfilling the mitzva. Rav Yehuda said that Shmuel said: The minimum measure of a myrtle branch and a willow branch is three handbreadths. And the minimum measure of a lulav is four handbreadths. The difference between the measures is so that the lulav will extend at least one handbreadth from the myrtle branch.

And Rabbi Parnakh said that Rabbi Yoḥanan said: The spine of the lulav, and not merely its leaves, must be at least four handbreadths long, so that it will extend from the myrtle branch at least one handbreadth.

The Gemara asks: Didn’t we learn in the mishna: A lulav that has three handbreadths in length, sufficient to enable one to wave with it, is fit for use in fulfilling the mitzva? That indicates that a lulav three handbreadths long is fit. The Gemara answers: Emend the language of the mishna and say: A lulav that has three handbreadths and an additional handbreadth that is sufficient to enable one to wave with it is fit. This emendation is understood by each amora according to his opinion. It is understood by this Sage, Shmuel, as per his opinion that only one additional handbreadth is required including the leaves; and it is understood by this Sage, Rabbi Yoḥanan, as per his opinion that the additional handbreadth must be in the length of the spine of the lulav, and the leaves are not taken into consideration.

The Gemara cites proof from a baraita. Come and hear: The minimum measure of a myrtle branch and of a willow branch is three handbreadths, and that of a lulav is four handbreadths. What, is it not that this measure is calculated with the leaves, in accordance with the opinion of Shmuel? The Gemara rejects this proof: No, it can be understood that the measure is calculated without the leaves.

Apropos the baraita cited above, the Gemara discusses the matter itself. The minimum measure of a myrtle branch and of a willow branch is three handbreadths, and that of a lulav is four handbreadths. Rabbi Tarfon says: With a cubit of five handbreadths. The preliminary understanding of Rabbi Tarfon’s opinion is that the minimum measure of a myrtle branch is five handbreadths, not three.

Rava said: May his Master, the Holy One, Blessed be He, forgive Rabbi Tarfon for this extreme stringency. Now, we do not find even a dense-leaved myrtle branch three handbreadths long; is it necessary to say that finding one five handbreadths long is nearly impossible?

When Rav Dimi came from Eretz Yisrael to Babylonia, he said that this is the correct understanding of the statement of Rabbi Tarfon: Take a cubit of six handbreadths, and render it a cubit of five handbreadths. Rabbi Tarfon is saying that for the purpose of measuring the myrtle branch, willow branch, and lulav, the standard six-handbreadth cubit is divided into five handbreadths, each slightly larger than the standard handbreadth. Take three of these large handbreadths for the myrtle branch, and three of these handbreadths plus the extra handbreadth for the lulav. The Gemara calculates: How many standard handbreadths are there in the minimum measure of a myrtle branch or willow branch? There are three and three-fifths standard handbreadths.

However, on that basis, there is a difficulty, as one statement of Shmuel contradicts another statement of Shmuel. Here, Rabbi Yehuda said that Shmuel said: The minimum measure of the myrtle branch and of the willow branch is three handbreadths, and there, Rav Huna said that Shmuel said: The halakha is in accordance with the opinion of Rabbi Tarfon, who requires a larger handbreadth. There is a discrepancy of three-fifths of a handbreadth between the measures. The Gemara answers: When Shmuel said that the measure is three handbreadths, he was not precise and merely approximated the measure. The Gemara asks: Say that we say: He was not precise when the approximation leads to stringency, but when it leads to leniency, do we say: He was not precise? That would result in using an unfit myrtle branch in performing a mitzva.

When Rabin came from Eretz Yisrael to Babylonia, he said that this is the correct understanding of the statement of Rabbi Tarfon: Take a cubit of five handbreadths, and render it a cubit of six handbreadths. Rabbi Tarfon said that for the purpose of measuring the myrtle branch, willow branch, and lulav, a five-handbreadth cubit is divided into six handbreadths, each slightly smaller than the standard handbreadth. Take three of these smaller handbreadths for the myrtle branch, and three of these handbreadths plus the extra handbreadth for the lulav. The Gemara calculates: How many standard handbreadths are there in the minimum measure of a myrtle branch or willow branch? There are two and a half standard handbreadths.

The Gemara asks: Ultimately, there remains a difficulty, as one statement of Shmuel contradicts another statement of Shmuel. In one statement he said the minimum measure of a myrtle branch is two and a half handbreadths, and in another he said that the measure is three handbreadths. The Gemara answers: When Shmuel said that the measure is three handbreadths, he was not precise and merely approximated the measure. And this is a case of: He was not precise, where the approximation leads to a stringency, as Rav Huna said that Shmuel said: The halakha is in accordance with the opinion of Rabbi Tarfon. Shmuel holds that the actual measure required is two and a half handbreadths, and he rounded it off to three, which is a more stringent measure.

MISHNA: A myrtle branch that was stolen or that is completely dry is unfit. A myrtle branch of a tree worshipped as idolatry [asheira] or a myrtle branch from a city whose residents were incited to idolatry is unfit. If the top of the myrtle branch was severed, if the leaves were severed completely, or if its berries were more numerous than its leaves, it is unfit. If one diminished their number by plucking berries so that they no longer outnumbered the leaves, the myrtle branch is fit. But one may not diminish the number on the Festival itself.

GEMARA: The Sages taught: It is written: ''Boughs of a dense-leaved tree'' (Leviticus 23:40); this is referring to a tree whose leaves obscure its tree. And which tree is that? You must say it is the myrtle tree. The Gemara suggests: And say it is the olive tree, whose leaves obscure the tree. The Gemara answers: We require a ''dense-leaved'' tree, whose leaves are in a chain-like configuration, and that is not the case with an olive tree.

The Gemara suggests: And say it is the Oriental plane tree, whose leaves are in a braid-like configuration. The Gemara answers: We require a tree whose leaves obscure its tree, and that is not the case with an Oriental plane tree.

The Gemara suggests: And say the verse is referring to oleander, which has both characteristics. Abaye said: It is written with regard to the Torah: ''Its ways are ways of pleasantness'' (Proverbs 3:17), and that is not the case with the oleander tree, because it is a poisonous plant and its sharp, thorn-like leaves pierce the hand of one holding it. Rava said: The unfitness of the oleander is derived from here: ''Love truth and peace'' (Zechariah 8:19), and poisonous plants that pierce are antithetical to peace.

The Sages taught: Plaited like a braid and chain-like; that is characteristic of the myrtle branch used in the fulfillment of the mitzva. Rabbi Eliezer ben Ya’akov says another characteristic. It is written: ''Boughs of a dense-leaved tree,'' indicating a tree that the taste of its branches and the taste of its fruit are alike. You must say this is the myrtle branch.

A Sage taught in the Tosefta: A dense-leaved branch is fit, and one that is not dense-leaved is unfit, even though it is a myrtle branch.

The Gemara asks: What are the circumstances of ''dense-leaved tree''? Rav Yehuda said: And it is a configuration where three leaves emerge from each base. Rav Kahana said: Even two leaves emerging from one base and one leaf that covers the other two emerging from a lower base is called thick. Rav Aḥa, son of Rava, would purposely seek a myrtle branch configured with two leaves emerging from one base and one emerging from a lower base, since this statement emerged from the mouth of Rav Kahana. Mar bar Ameimar said to Rav Ashi: My father called a myrtle branch with that configuration a wild myrtle branch.

The Sages taught: If most of its leaves fell and only a minority of the leaves remained, the myrtle branch is fit, provided that its dense-leaved nature remains intact.

The Gemara wonders: This matter itself is difficult, as there is an internal contradiction in this baraita. On the one hand, you said: If most of its leaves fell it is fit, and then the baraita taught: Provided that its dense-leaved nature remains intact. Once two of every three leaves fell, how can you find a branch whose dense-leaved nature is intact?

Abaye said: You can find it
