One of the Rabbinic concepts with which I have been deeply taken appears twice in Masechet Shabbat:
Shabbat 10a
Every judge who judges with complete fairness even for a single hour, the Writ gives him credit as though he had become a Partner to the Holy One, Blessed Be He, in the Creation. (For) here it is written, (Shemot 18:13) “And the people stood about Moshe from the morning into the evening”; whilst elsewhere it is written, (Beraishit 1:5) “And there was morning, and there was evening, one day.”
Ibid. 119b
R. Hamnuna said: He who prays on the eve of Shabbat and recites (Beraishit 2:1) “And (the heaven and the earth) were finished,” the Writ treats of him as though he had become a Partner with the Holy One, Blessed Be He, in the Creation, for it is said, (Ibid.) “VaYechulu (and they were finished);” read not “VaYechulu” but “VaYechalu (and they finished).”
