Which rabbi from Torah vodaas? What was the story?
Are you claiming that when one of the chachamim argued with their teacher (in gemara let’s say), the argument was “my teacher, you are mistaken what Hashem informed Moshe on har Sinai, the halacha was actually said over this way….”?
I believe that arguments amongst chaza”l were as follows: “my teacher, you are mistaken in your conclusion according to the Klalim (rules) that Hashem gave Moshe on Har Sinai. If you look closely, the rules should result in a different law – unlike the one you taught”
Meaning, Hashem did NOT give every detail to Moshe. He gave Klalim on how to develop the laws in the Torah.
