Deuteronomy 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). ושמרת ועשית אותם THOU SHALT THEREFORE KEEP AND DO THEM — A heavenly voice (בת קול) pronounces by these words a blessing upon him (the worshipper): “You have brought the first fruits today — you will be privileged to do so next year, too!” (Midrash Tanchuma, Ki Tavo 1).

הַיּ֣וֹם הַזֶּ֗ה יְהֹוָ֨ה אֱלֹהֶ֜יךָ מְצַוְּךָ֧ לַעֲשׂ֛וֹת אֶת־הַחֻקִּ֥ים הָאֵ֖לֶּה וְאֶת־הַמִּשְׁפָּטִ֑ים וְשָׁמַרְתָּ֤ וְעָשִׂ֙יתָ֙ אוֹתָ֔ם בְּכׇל־לְבָבְךָ֖ וּבְכׇל־נַפְשֶֽׁךָ׃

This day the Lord thy God has commanded thee to do these statutes and judgments: thou shalt therefore keep and do them with all thy heart, and with all thy soul.
