Some Tu B'Shevat Sources

(1) There are four new years:The first of Nisan is the new year for kings and for festivals. The first of Elul is the new year for the tithe of beasts. Rabbi Elazar and Rabbi Shimon say: the first of Tishri. The first of Tishri is the new year for years, for shmitta and jubilee years, for planting and for [tithe of] vegetables. The first of Shevat is the new year for trees, according to the words of Bet Shammai. Bet Hillel says: on the fifteenth of that month.

(19) When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by wielding an axe against them; for thou mayest eat of them, but thou shalt not cut them down; for is the tree of the field man, that it should be besieged of thee? (20) Only the trees of which thou knowest that they are not trees for food, them thou mayest destroy and cut down, that thou mayest build bulwarks against the city that maketh war with thee, until it fall.

And every growth/si’ach of the field” [Gn 2:5]—All the trees as it were /k’ilu are conversing/m’sichin, these with these. All the trees as it were are conversing with the creatures / `im hab’riyot. All the trees were created to give pleasure to the creatures . . . All the conversations of the creatures are about nothing except the land . . . and all the prayers of the creatures are about nothing except the land . . . All the prayers of Israel are about nothing except the Temple/ beyt hamiqdash.

Why were matters of Torah compared to a fig tree? Just as this fig tree, whenever a person searches it for figs to eat, he finds figs in it, as the figs on a tree do not ripen all at once, so that one can always find a recently ripened fig, so too, with matters of Torah. Whenever a person meditates upon them, he finds in them new meaning.

Composed in Middle-Age Spain (c.1255 - c.1285 CE). The Sefer ha-Hinukh (Book of Education), is a work which systematically discusses the 613 commandments of the Torah. It was published anonymously in 13th century Spain. The work's enumeration of the commandments is based upon Maimonides' system of counting as per his Sefer Hamitzvot; each is listed according to its appearance in the weekly Torah portion and the work is structured correspondingly. It separately discusses each of the 613 commandments, both from a legal and a moral perspective. For each, the discussion starts by linking the mitzvah to its Biblical source, and then addresses the philosophical underpinnings of the commandment. Following this, it presents a brief overview of the halakha (practical Jewish law) governing its observance - usually based on Maimonides' Mishneh Torah - and closes with a summary as to the commandment's applicability.

(1) To not destroy fruit trees: That we have been prevented from chopping down trees when we besiege a city to distress the people of the city and to sadden their hearts. And about this is it stated (Deuteronomy 20:19), "you may not destroy its tree, etc. and you shall not chop it down." And likewise not to do any damage - such as burning or ripping a garment or breaking a vessel for no reason - entered under this negative commandment And in all of these matters and in all that is similar to them, they, may their memory be blessed, would always say in the Gemara (Kiddushin 32a), "But behold, he is transgressing on account of 'do not destroy.'" And nonetheless we only administer lashes for one that cuts down a fruit tree, since it is explicit in Scripture. But with other destructions, we [only] give him lashes of rebellion (See Mishneh Torah, Laws of Kings and Wars 6:10).

(2) The root of this commandment is well-known - it is in order to teach our souls to love good and benefit and to cling to it. And through this, good clings to us and we will distance [ourselves] from all bad and destructive things. And this is the way of the pious and people of [proper] action - they love peace and are happy for the good of the creatures and bring them close to Torah, and they do not destroy even a grain of mustard in the world. And they are distressed by all loss and destruction that they see; and if they can prevent it, they will prevent any destruction with all of their strength. But not so are the wicked - the brothers of the destructive spirits. They rejoice in the destruction of the world, and they destroy themselves - [since] in the way that a person measures, so is he measured; which is to say that he clings to it forever, as the matter that is written (Proverbs 17:5), "the one who rejoices in calamity, will not be cleared (of evil)." And the one who desires the good and rejoices in it, 'his soul will dwell in the good' forever. This is known and famous.

(3) From the laws of the commandment is that which they, may their memory be blessed, said (Bava Kamma 91b) that the Torah only forbade cutting fruit trees when he cuts it down destructively. But it is certainly permitted to cut [them] if he finds a beneficial matter in it, such as the value of the wood become valuable and he wants to sell it; or to remove injury by cutting them, such as [if] it was damaging other trees better than it, or because it was damaging other fields. In all of these angles and in all that is similar to it, it is permissible. And they, may their memory be blessed, said (Bava Kamma 91b) that it is permitted to cut any non-fruit bearing tree - even when he does not need [its wood] - and [likewise] any fruit tree that is very old, to the point that it only gives a few fruit, for the sake of which it is not worthwhile to toil [on it]. And they, may their memory be blessed, said with an olive tree, it is permitted to cut anything that makes less than a fourth [of a kav]; and with a palm tree, less than a kav of dates.

(4) And in general, they, may their memory be blessed, forbade to do anything destructive. And they said about anyone who destroys anything out of rage (Shabbat 105a) that he is like one who worships idolatry, as so is the way of the evil impulse: Today it says to him, "Do this"; and if he trusts it, tomorrow, it will say to him, "Go and worship idolatry" - meaning to say that every person is obligated to rebuke his impulse and to conquer his desire to the point that he makes the intellectual soul dominate the desiring soul, until it becomes its maidservant and [the intellect] dominate it forever and ever. However, they brought in the Gemara (Shabbat 105a) stories of a few sages that showed themselves to be angry and they would throw down some food or some thing from their hand, in order to discipline the members of their household and to give them alacrity. Nonetheless their supervision would always be over them, that they not throw down something that would be destroyed by this. And the rest of the details of the commandment are in the second chapter of Bava Batra (see Mishneh Torah, Laws of Kings and Wars 7).

(5) And this prohibition is practiced in every place and at all times by males and females. And one who transgresses it and destroys fruit trees has violated this negative commandment and is liable for lashes. And for other destruction on other things that are not explicit, we lash him [with] lashes of rebellion.

Honi the Circle Maker

One day, Honi was walking along the road when he saw a certain man planting a carob tree. Ḥoni said to him: This tree, after how many years will it bear fruit? The man said to him: It will not produce fruit until seventy years have passed. Ḥoni said to him: Is it obvious to you that you will live seventy years, that you expect to benefit from this tree? He said to him: That man himself found a world full of carob trees. Just as my ancestors planted for me, I too am planting for my descendants.
