פירוש על דברים 26:16

היום הזה ה׳ אלהיך מצוך THIS DAY THE LORD THY GOD COMMANDETH THEE — This suggests: each day they (God’s commandments) should be to you as something new (not antiquated and something of which you have become tired), as though you had received the commands that very day for the first time (Midrash Tanchuma, Ki Tavo 1; cf. Rashi on Deuteronomy 11:13).

THIS DAY THE ETERNAL THY G-D COMMANDETH THEE TO DO THESE STATUTES AND ORDINANCES. Now Moses finished explaining the Torah to them and issuing all the new commandments which G-d commanded him to declare to them. Therefore he said, “This day the Eternal thy G-d commandeth thee to do these statutes and ordinances, for I have already completed everything for you.” He mentioned, and thou shalt observe and do them with all thy heart, and with all thy soul.⁴¹In Verse 16 before us. I have already explained the terms “heart” and “soul.”⁴²Above, 6:5.

היום הזה, that You entered into the covenant with him. The “covenant” comprised the undertaking by Israel to keep G’d’s statutes as something that would ensure their welfare, something He had not done for any other nation.
