Proverbs
Proverbs 10:25
The verse 'V'tzaddik yesod olam' — 'the righteous one is the foundation of the world' — becomes the primary biblical anchor for the Kabbalistic sefirah of Yesod, identifying it with the Tzaddik archetype.
כַּעֲב֣וֹר ס֭וּפָה וְאֵ֣ין רָשָׁ֑ע וְ֝צַדִּ֗יק יְס֣וֹד עוֹלָֽם׃
When the storm passes a wicked person is gone, But the righteous person is an everlasting foundation.
Why it matters — This verse is the most cited biblical source for Yesod, connecting the concept of the righteous person as the channel and foundation through which divine blessing flows into the world.
