The entire incident of the Flood seems perplexing. Humanity had started populating the world, and initially fulfilled Gods mission, until suddenly, things came to a bottleneck, and society degenerated to a point where God decided to “start over” from Noach. But why?
The Malbim observes that the Torah writes:
צֵא, מִן-הַתֵּבָה–אַתָּה… כָּל-הַחַיָּה אֲשֶׁר-אִתְּךָ מִכָּל-בָּשָׂר, בָּעוֹף וּבַבְּהֵמָה וּבְכָל-הָרֶמֶשׂ הָרֹמֵשׂ עַל-הָאָרֶץ–הוצא (הַיְצֵא) אִתָּךְ; וְשָׁרְצוּ בָאָרֶץ, וּפָרוּ וְרָבוּ עַל-הָאָרֶץ – Leave the Ark – you… Every living creature with you. Every creature, bird, animal and insect that creeps on the earth, should leave with you, and they will multiply and infest the earth. (8:16-17)
Malbim explains that the salvation of life on earth was through Noach, and the psukim say as much, by emphasising כָּל-הַחַיָּה אֲשֶׁר-אִתְּךָ – he was the instrument through which they were saved, because they were “with him”.
The Malbim explains the undercurrent in the sequence of events that led to the Flood, and what it repaired. When Adam was created, he had the potential of all Creation within him. Every possible characteristic and outcome was seeded within him, including those of animals. The way he behaved; nature reacted. We see this somewhat today, to a small degree, in how pets reflect characteristics of their owners.
The generation of the Flood squandered and destroyed their potential to be good, and had no positive characteristics. Nature reacted accordingly, and animals became evil too, with all species mingling with others, to a point where the Torah (6:12) writes כִּי-הִשְׁחִית כָּל-בָּשָׂר אֶת-דַּרְכּוֹ, עַל-הָאָרֶץ – that every living creature had lost its way.
Noach reclaimed decency, and “humanity” – in the true sense of the word, by being honest and good. He reclaimed the potential to be good. He was the sole being that had not corrupted itself, and as such existence was perpetuated solely for his sake. This is why he was chosen of all men – existence owed itself to him.
צֵא, מִן-הַתֵּבָה–אַתָּה… כָּל-הַחַיָּה אֲשֶׁר-אִתְּךָ מִכָּל-בָּשָׂר, בָּעוֹף וּבַבְּהֵמָה וּבְכָל-הָרֶמֶשׂ הָרֹמֵשׂ עַל-הָאָרֶץ–הוצא (הַיְצֵא) אִתָּךְ; וְשָׁרְצוּ בָאָרֶץ, וּפָרוּ וְרָבוּ עַל-הָאָרֶץ – Leave the Ark – you… Every living creature with you. Every creature, bird, animal and insect that creeps on the earth, should leave with you, and they will multiply and infest the earth. (8:16-17)
Nature owed Noach a debt – it was preserved through him. In the beginning of the very next chapter, God permits man to eat meat for the very first time – as a direct result of this.
