וידבר אלהים AND GOD SPAKE — The word אלהים is a term for a judge. Since there are chapters in the Torah of such a character that if a person observes the commands contained therein he will receive a reward and if he never observes them at all) he will not receive punishment on their account, one might think that the Ten Commandments are also of such a character (that no punishment will follow upon the infringement of them); therefore Scripture expressly states, “God spake” — God Who is Judge, exacting punishment (Mekhilta d'Rabbi Yishmael 20:1:1).
אשר הוצאתיך מארץ מצרים. כְּדַאי הִיא הַהוֹצָאָה שֶׁתִּהְיוּ מְשֻׁעְבָּדִים לִי; דָּ"אַ, לְפִי שֶׁנִּגְלָה בַיָּם כְּגִבּוֹר מִלְחָמָה וְנִגְלָה כָּאן כְּזָקֵן מָלֵא רַחֲמִים,
אשר הוצאתיך מארץ מצרים WHO HAVE BROUGHT THEE OUT OF THE LAND OF EGYPT — That act of bringing you out is alone of sufficient importance that you should subject yourselves to Me. Another explanation: because He had revealed Himself to them at the Red Sea as a mighty man of war and here He revealed Himself as a grey-beard filled with compassion,
אנכי ה' אלהיך הדבור הזה מצות עשה, אמר אנכי ה', יורה ויצוה אותם שידעו ויאמינו כי יש ה', והוא אלהים להם, כלומר הווה, קדמון, מאתו היה הכל בחפץ ויכולת, והוא אלהים להם, שחייבים לעבוד אותו.
..."I am Hashem your God:" This statement is a positive commandment, as it says, "I am Hashem, who teaches and commands you that you should know and believe that there is a Hashem, and He is your God," that is to say, He existed before, from Him came everything by means of his desire [i.e., He created the world because He wanted to, not by accident] and capability, and He is your God, so you are required to serve Him.
אלהים אחרים. שֶׁאֵינָן אֱלוֹהוּת אֶלָּא אֲחֵרִים עֲשָׂאוּם אֱלֹהִים עֲלֵיהֶם, וְלֹא יִתָּכֵן לְפָרֵשׁ אֱלֹהִים אֲחֵרִים זוּלָתִי, שֶׁגְּנַאי כְּלַפֵּי מַעְלָה לִקְרֹאותָם אֱלוֹהוּת אֶצְלוֹ.
אלהים אחרים OTHER GODS — which are not gods, but others have made them gods over themselves. It would not be correct to explain this to mean “gods other than Me”, for it would be blasphemy of the Most High God to term them gods together with Him (cf. Mekhilta d'Rabbi Yishmael 20:3:1).
זכור. זָכוֹר וְשָׁמוֹר בְּדִבּוּר אֶחָד נֶאֶמְרוּ
זכור — This word REMEMBER which opens this commandment here and שמור “observe” which opens it in Deuteronomy (5:12) were spoken in one utterance.
אתה ובנך ובתך. אֵלּוּ קְטַנִּים; אוֹ אֵינוֹ אֶלָּא גְּדוֹלִים?
אתה ובנך ובתך THOU AND THY SON AND THY DAUGHTER — these latter mean the young children. Or perhaps this is not so, but it means your adult children? abbi Yishmael 20:10:1).
ואהבת אביו ואמו תהיה על דרך זה: שיחשוב שגידלוהו, וטרחו בו ללמדו דרכי השם יתברך, והורוהו וחנכוהו לתורה ולמצוות.
And love for father and mother should be in this manner — that he should be ever mindful that they reared him and exerted themselves to teach him the ways of the Lord, may He be Blessed, and instructed him and educated him as to Torah and Commandments
לא תחמוד. אנשים רבים יתמהו על זאת המצוה. איך יהיה אדם שלא יחמוד דבר יפה בלבו כל מה שהוא נחמד למראה עיניו.
You shall not covet: Many people have wondered about this commandment, how is is that a man not covet in his heart that which is beautiful [and] all that which appears pleasant in his eyes.
