Deuteronomy 11:22

שמר תשמרון [IF] YE SHALL DILIGENTLY OBSERVE [ALL THESE COMMANDMENTS] — The repetition of the verb implies an admonition to be very much on one’s guard: to be careful in respect to one’s study of the Torah that it should not be forgotten (cf.

Is He not “a consuming fire” (Deuteronomy 4:24)? But it means: cleave to the scholars and sages, and I will account it unto you as though you cleave to Him (Sifrei Devarim 49:2).

כִּי֩ אִם־שָׁמֹ֨ר תִּשְׁמְר֜וּן אֶת־כׇּל־הַמִּצְוָ֣ה הַזֹּ֗את אֲשֶׁ֧ר אָנֹכִ֛י מְצַוֶּ֥ה אֶתְכֶ֖ם לַעֲשֹׂתָ֑הּ לְאַהֲבָ֞ה אֶת־יְהֹוָ֧ה אֱלֹהֵיכֶ֛ם לָלֶ֥כֶת בְּכׇל־דְּרָכָ֖יו וּלְדׇבְקָה־בֽוֹ׃

For if you shall diligently keep all these commandments which I command you, to do them, to love the Lord your God, to walk in all his ways, and to hold fast to him;
