נֹחַ אִישׁ צַדִּיק תָּמִים הָיָה בְּדֹרֹתָיו
“Noach was a righteous man, a person of integrity in his generation.”
(BEREISHIT 6:9)
Rabbi Sacks teaches us:
“Throughout the whole of the narrative - the warning of the Flood, the building of the Ark, the gathering of animals, the beginning of the rain - Noach says nothing... he has no impact on his contemporaries. He does not engage with them, rebuke them, or urge them to mend their ways. Nor does he pray for them, or question the justice of the Flood... [Noach] fails to show collective responsibility.”
To Heal A Fractured World, pp. 140-141
Rabbi Sacks further teaches explains:
“The Torah sets a high standard for the moral life. It is not enough to be righteous if that means turning our backs on a society that is guilty of wrongdoing. We must take a stand. We must protest... even if the likelihood of changing minds is small. That is because the moral life is a life we share with others. We are, in some sense, responsible for the society of which we are a part. It is not enough to be good. We must encourage others to be good. There are times when each of us must lead.”
