וַיֹּ֤אמֶר אֲלֵהֶם֙ שִׂ֣ימוּ לְבַבְכֶ֔ם לְכָל־הַדְּבָרִ֔ים אֲשֶׁ֧ר אָנֹכִ֛י מֵעִ֥יד בָּכֶ֖ם הַיּ֑וֹם אֲשֶׁ֤ר תְּצַוֻּם֙ אֶת־בְּנֵיכֶ֔ם לִשְׁמֹ֣ר לַעֲשׂ֔וֹת אֶת־כָּל־דִּבְרֵ֖י הַתּוֹרָ֥ה הַזֹּֽאת׃
Y díjoles: Poned vuestro corazón á todas las palabras que yo os protesto hoy, para que las mandéis á vuestros hijos, y cuiden de poner por obra todas las palabras de esta ley.

In sum: One must take care to fulfill the words of the Torah, both those things between man and his Maker and those things between man and his neighbor. For they are all the word of the L-rd, as it is written (Devarim 32:46-47): "…which you are to command your children to keep and to do — all the words of this Torah. For it is not an empty thing for you. For it is your life." For just as with the body there is life in every limb, and all [of the limbs] are required by it, so, in every mitzvah there is life for a man's soul and all [the mitzvoth] are required by it. This is the intent of Koheleth 12:13: "The end of the matter — all has been heard. Fear G-d and keep His mitzvoth. For this is the whole man." That is, through the fear of G-d, not to transgress any negative commandment and to fulfill all of His positive commandments — this is the whole man. That is, then the man is called "complete," which is not so if some mitzvah is minor in his eyes, G-d forbid, in which instance he is lacking in his soul.
