רַ֚ק אִם־שָׁמ֣וֹעַ תִּשְׁמַ֔ע בְּק֖וֹל יְהוָ֣ה אֱלֹהֶ֑יךָ לִשְׁמֹ֤ר לַעֲשׂוֹת֙ אֶת־כָּל־הַמִּצְוָ֣ה הַזֹּ֔את אֲשֶׁ֛ר אָנֹכִ֥י מְצַוְּךָ֖ הַיּֽוֹם׃
somente se deres ouvidos à voz do Eterno teu Deus, para guardares e cumprires todos estes mandamentos que hoje te ordeno.
Sifrei Devarim
(Devarim 15:5) "Only if you hearken to the voice of the L-rd your G-d": From here they stated: If a man hearkens but a little, he is given to hear much. If he hearkens to the words of Torah, he is given to hear the words of the scribes.
