כַּעֲב֣וֹר ס֭וּפָה וְאֵ֣ין רָשָׁ֑ע וְ֝צַדִּ֗יק יְס֣וֹד עוֹלָֽם׃
װי אַ שטורעם גײט אַריבער, אַזױ איז דער רָשע ניטאָ, אָבער דער צדיק איז אַן אײביקער גרונטפֿעסט.
Zohar
NOAH WAS A RIGHTEOUS MAN. Assuredly so, after the supernal pattern. It is written, “The Righteous one is the foundation of the world” (Prov. 10, 25), and the earth is established thereon, for this is the pillar that upholds the world. So Noah was called Zaddik (righteous) below.
Sha'arei Orah
Furthermore, this quality is called Yesod-Foundation-יסוד, that is, just as a house, rests upon its foundations, so also, HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י rests upon His quality of Foundation-Yesod-יסוד, being that His quality of Lordship-Adona”y-אדנ"י receives no influence and existence except through the quality of Foundation-Yesod-יסוד, which is called the Living God-E”l Chai-א"ל חי. In the Talmud, in Tractate Chagigah24Chagigah 12b the sages said, “Upon what is the world established? Upon a single pillar called the Righteous-Tzaddik-צדיק, as it states,25Proverbs 10:25 “The righteous-Tzaddik-צדיק is the Yesod-Foundation-יסוד of the world.”
Sha'arei Orah
Now, throughout the Torah this quality is called The Righteous One-Tzaddik-צדיק. Moreover, because it is called the Foundation-Yesod-יסוד and carries all entities that are below it, it is called,30Proverbs 10:25 “the Righteous One-Tzaddik-צדיק, the Foundation-Yesod-יסוד of the world.” The reason it is called Righteous-Tzaddik-צדיק is because it influences all goodness and blessings into HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י, as it states,31Psalms 37:21 “the righteous-Tzaddik-צדיק is generous and gives.”
