What endures from all of this is a teaching that speaks to every Yid in every generation. The root of Kayin's sin - of Korach's sin - was not ambition or even wickedness in the ordinary sense. It was the failure of hachna'ah, of that inner bending before something greater than oneself. Kayin's offering was rejected, and he could not bear it. Korach saw greatness bestowed upon others, and felt only its sting. Both had hearts that ruled them, rather than hearts they ruled.
Yisro shows us that having the same root as Korach does not guarantee failure; it merely defines the battlefield. He bent his pride and gave his daughter, and by extension, himself, meriting to mend an ancient sin. Channah showed us the same - in her silence before Peninnah, in her weeping before Hashem, in the extraordinary act of turning her pain to Hashem where retaliation was only natural.
May we, the children of Avraham, Yitzchak, and Yaakov - who are defined by the middos of anavah and hachna'ah - learn to hold our hearts in our own hands. May we greet the final geulah with hearts already softened and already returned - as the Navi says (יחזקאל לו כו): וְנָתַתִּי לָכֶם לֵב חָדָשׁ וְרוּחַ חֲדָשָׁה אֶתֵּן בְּקִרְבְּכֶם וַהֲסִרֹתִי אֶת־לֵב הָאֶבֶן מִבְּשַׂרְכֶם וְנָתַתִּי לָכֶם לֵב בָּשָׂר - And I will give you a new heart and put a new spirit into you: I will remove the heart of stone from your body and give you a heart of flesh.
א גוּט שַׁבָּת
