RABBINICAL JUDAISM TEACHES THAT WHEN TWO RABBIS HAVE DIFFERENT OPINIONS THAT BOTH OPINIONS ARE FROM YHVH

Talmud: Eiruvin 13b

R. Abba stated in the name of Samuel: For three years there was a dispute between Beth Shammai and Beth Hillel, the former asserting, ‘The halachah is in agreement with our views’ and the latter contending, ‘The halachah is in agreement with our views’. Then a bath kol [heavenly voice] issued announcing, ‘[The utterances of] both are the words of the living God but the halachah is in agreement with the rulings of Beth Hillel’.
