Дварим 6:24 Галаха: Mishneh Torah, Repentance & Sefer HaChinukh

Now, after it is known that the reward and the good which we will acquire for observing the precepts and the way of the Lord according to what it is written in the Torah consist of life in the World to Come, even as it is said: "That it may be well with thee, and that thou mayest prolong thy days" (Deut. 22.7), and that the punishment inflicted upon the wicked who abandoned the righteous paths described in the Torah consists of excision, even as it is said: "That soul shall be utterly cut off; his iniquity shall be upon him" (Num.15.31), what is this which it is written throughout the Torah, if ye will hearken you will be overtaken by thus, but if ye will not hearken you will be met with such, and all those things are in this world, for instance, plenty, famine, war, peace, government, oppression, permanency in the land, exile, success in undertakings, its failure, and other similar text in the Covenant? All those things were and will be true, and as long as we observe the precepts of the Torah all the good of this world will overtake us, and as long as we transgress them we will be met by those evil things described therein. Nevertheless, neither are those good things the end of the reward for observing the commandments nor are those evil things the end of the punishment to be inflicted upon one who violates the precepts. For so are all these matters balanced: The Holy One, blessed is He! bestowed upon us this Torah as a tree of life, and whosoever conducts himself after the prescribed order therein, and studies to know it with a complete and upright knowledge, he acquires therewith life in the World to Come. And, in the measure of his works and wisdom he obtains his acquisition. We were moreover, assured in the Torah that if we will observe it in joy and out of goodness of soul, and constantly meditate in its wisdom, He will detach from us all such things which prevent us from observing it, such as sickness, war, famine and the like. He will, in addition thereto, be bountiful unto us by giving us all good which sustain our hands to observe the Torah, as plenty, peace, and an increase in silver and gold, so that we be not occupied all of our days in the things that are of bodily need, but, instead, be at leisure to study wisdom and observe the precept in order to acquire life in the World to Come. Even so it is said in the Torah: "And it shall be our righteousness, if we observe to do all these commandments, before the Lord our God, as He hath commanded us" (Deut. 6.24–25). He made likewise known to us, that if we will purposely abandon the Torah, and busy ourselves with the vanities of the times, as the subject is spoken of, saying: "But Jeshurun waxed fat, and kicked (Ibid. 32.15). The True Judge will detatch from the forsakers all the good of this world which had strengthened their hands so that they kicked, and bring upon them all the evil to prevent them from acquiring the World to Come, so that they be lost in their wickedness. This is as it is written in the Torah: "Because thou didst not serve the Lord thy God with joyfulness, and with gladness of heart, by reason of the abundance of all things; therefore shalt thou serve thine enemy who the Lord shall send against thee" (Ibid. 28. 46–47) Consequently, the interpretation of all those blessings and curses is this way: As if saying, if you have served the Lord with joyfulness and observed His way, he will bestow in abundance these blessings upon you and set at a distance the curses from you, so that you be at leisure to grow wise in the wisdom of the Torah, and to busy yourselves therein, and so that you will merit life in the World to Come, and to do you good in the world which is all good, and prolong your days in the world which is unending, and you will find yourselves acquiring two worlds, to good living in this world, which will bring to a life in the World to Come, for if one does not acquire wisdom and good works here he has nothing else to acquire it with, even as it said: "For there is no work, no device, no knowledge nor wisdom in the grave (Ecc. 9.10). But if you have forsaken the Lord, and did err in eating drinking and prostitution, and their like, he will bring upon you those curses and detach from you all blessings until you will end your days in confusion and dread, and your will have neither a heart of leisure nor a sound body to perform the precepts, so that you lose the life in the World to Come, as a consequence whereof you will have lost two worlds; for, as long as a man is occupied in this world with sickness, war and hunger he can not be engaged either in wisdom or in precepts, by which to acquire the World to Come.

Behold, they elucidated that even the lulav and the sukkah and tefillin — that He commanded that they be “a sign upon your arm and a commemoration between your eyes [...] that the Lord took you out of Egypt with a strong hand” (Exodus 13:9) — are not for the honor of God, may He be blessed, but [rather] to have mercy on our souls. And they already set this into the prayer of Yom Kippur, “You have separated man from the start and recognized him to stand in front of You, as who will say to You what to do, and if he is righteous, what will he give to You?” And so [too], it stated in the Torah (Deuteronomy 10:13), “for your good”; and so [too] (Deuteronomy 6:24), “And He commanded us to do all of these statutes [...], for our good all of the days.” And the intention in all of them is that it be good for us and not for Him, may He blessed and elevated. But all that we are commanded is [so that] our souls be refined and purified without the dross of evil thoughts and disgusting character traits. And so that which they said (Berakhot 33a), “[It is because] he makes the traits of the Holy One, blessed be He into mercy and they are only decrees,” is to say that God did not worry about the nest of the bird and His “mercy did not reach” it and its child; as His mercy does not extend to creatures with an animal soul, to prevent us from doing what we need to them. As were it so, slaughtering would be forbidden. But [rather], the reason for the proscription is to teach us the trait of mercy and that we not become cruel. Since cruelty spreads in the soul of a man, as it is known with butchers that slaughter large oxen and donkeys, that they are “people of blood,” “slaughterers of men” [and] very cruel. And because of this they said (Kiddushin 82a), “The best of butchers are the partners of Amalek.” And behold, these commandments with animals and birds are not mercy upon them, but [rather] decrees upon us, to guide us and to teach us the good character traits. To here are the interpretations of Ramban, may his memory be blessed.
