כָּל־הַמִּצְוָ֗ה אֲשֶׁ֨ר אָנֹכִ֧י מְצַוְּךָ֛ הַיּ֖וֹם תִּשְׁמְר֣וּן לַעֲשׂ֑וֹת לְמַ֨עַן תִּֽחְי֜וּן וּרְבִיתֶ֗ם וּבָאתֶם֙ וִֽירִשְׁתֶּ֣ם אֶת־הָאָ֔רֶץ אֲשֶׁר־נִשְׁבַּ֥ע יְהוָ֖ה לַאֲבֹתֵיכֶֽם׃
Todos os mandamentos que hoje eu vos ordeno cuidareis de observar, para que vivais, e vos multipliqueis, e entreis, e possuais a terra que o SENHOR, com juramento, prometeu a vossos pais.
Shenei Luchot HaBerit
כל המצוה אשר אנכי מצוך היום . Our sages in Bereshit Rabbah 60,2 advise that having commenced to perform a מצוה one should try to complete it. This is the message contained in our verse (11,8). It is only called a מצוה when performed in full.
