(ט) אֵ֚לֶּה תּוֹלְדֹ֣ת נֹ֔חַ נֹ֗חַ אִ֥ישׁ צַדִּ֛יק תָּמִ֥ים הָיָ֖ה בְּדֹֽרֹתָ֑יו אֶת־הָֽאֱלקים הִֽתְהַלֶּךְ־נֹֽחַ׃
(א) אלה תולדת נח נח איש צדיק. דָּבָר אַחֵר לִמֶּדְךָ שֶׁעִקַּר תּוֹלְדוֹתֵיהֶם שֶׁל צַדִּיקִים מַעֲשִׂים טוֹבִים::
(1) אלה תולדת נח נח איש צדיק THESE ARE THE PROGENY OF NOAH: NOAH WAS A RIGHTEOUS MAN —Another explanation is: since after stating “These are the progeny of Noah”, it does not at once mention the names of his children but declares that he “was a righteous man”, Scripture thereby teaches you that the real progeny of righteous people are their good deeds (Genesis Rabbah 30:6).
(ב) ויצא. לֹא הָיָה צָרִיךְ לִכְתֹּב אֶלָּא וַיֵּלֶךְ יַעֲקֹב חָרָנָה, וְלָמָּה הִזְכִּיר יְצִיאָתוֹ? אֶלָּא מַגִּיד שֶׁיְּצִיאַת צַדִּיק מִן הַמָּקוֹם עוֹשָׂה רֹשֶׁם, שֶׁבִּזְמַן שֶׁהַצַּדִּיק בָּעִיר, הוּא הוֹדָהּ הוּא זִיוָהּ הוּא הֲדָרָהּ; יָצָא מִשָּׁם, פָּנָה הוֹדָהּ פָּנָה זִיוָהּ פָּנָה הֲדָרָהּ. וְ
(2) ויצא [AND JACOB] WENT OUT—It need have written simply “And Jacob went to Haran’’; why then does it mention his departure from Beersheba? But it intends to tell us that the departure of a righteous person from his city makes an impression. As long as a righteous man is in his city he is its glory and splendour and beauty; when he leaves it, there depart also its glory, its splendour and its beauty.
I heard the most incredible quote from my teacher, R' Beinish Ginsburg. He said that the passuk reads, "Eileh toldos Noach, Noach," to teach us that you are your most important descendent! Before you can raise children and grandchildren, you need to raise yourself, work on yourself. That's what the passuk is teaching us. The more you work on yourself, the more you'll be able to help your children and family as you get older. By treating yourself as your most important descendent, you can work on yourself, and the spiritual growth that you have will then impact all of your descendants, leaving tremendously positive ripple effects.
The Chiddushei HaRim, the first Gerrer Rebbe, is quoted as saying- "We say השמים שמים לה והארץ נתן לבני אדם, that the heavens are God's and the Earth He gave to man- He gave the earth to man so that man should make it heavenly." We have an obligation to leave behind Torah and kedusha, and the best way for us to do that is through our actions. When we work on ourselves and improve our actions, it will inspire many people. We will inspire ourselves to keep working, our children to emulate us, their friends to emulate them, and so on and so forth.
People know that they want to leave a legacy, for their children, family, and their communities. That legacy needs to start with you! So the more you work on yourself, the more that work will trickle down for generations to come. To quote R' Ginsburg quoting R' Avigdor Miller- there is no small step forward in ruchniyus, because ruchniyus lasts forever.
Start small. Take on one thing and make it a part of your essence, something that will make an impression on your family and children, your friends and your community. You'll be surprised at who you might inspire.
