Midrash su Salmi 90:12

(Fol. 12) R. Abdimi of the City Haifa, said: "Since the destruction of the Temple, prophecy has been withheld from the prophets and has been given to the wise." Is it then impossible for a wise man to be also a prophet? He means to say, that although it has been withheld from prophets, it is not being withheld from the wise ones. Amemar said: "And a wise man is to be preferred to a prophet, as it is said (Ps. 90, 12) Obtain a heart endowed with wisdom. And usually, who is dependent upon whom? The lesser is dependent upon the greater." Abaye said: "This theory may be supported by the fact that one great man declares something new, and exactly the same has been said by another great man." Raba said: "Why is it so difticult to understand such a thing? It may be that both of them are equal in wisdom. Therefore, said Raba, it happens frequently that a great man declares something new, and afterwards it is found (Ib. b) that R. Akiba b. Joseph [who is hardly his equal] has already declared so." R. Ashi, however, objected and said: "Why is it so difficult to understand such a thing? It may happen that in this one case he was equal in wisdom to him. "But," said R. Ashi, "I can support this from the fact that it very often occurs that a sage declares a Halacha, and afterwards the same is taught from Moses as delivered on Mount Sinai." And yet even then, it may be by chance, just as a blind man finds his way down from the opening of a roof.
