Еврейская мысль к Бамидбар 11:35

As for the principle which I laid down, that preparation and perfection of moral and rational faculties are the sine quâ non, our Sages say exactly the same: “The spirit of prophecy only rests upon persons who are wise, strong, and rich.” We have explained these words in our Commentary on the Mishnah, and in our large work. We stated there that the Sons of the Prophets were constantly engaged in preparation. That those who have prepared themselves may still be prevented from being prophets, may be inferred from the history of Baruch, the son of Nerijah; for he followed Jeremiah, who prepared and instructed him; and yet he hoped in vain for prophecy; comp., “I am weary with my sighing, and rest have I not found.” He was then told through Jeremiah, “Thus saith the Lord, Thus shalt thou say to him, Thou seekest for thee great things, do not seek” (Jer. 45:5). It may perhaps be assumed that prophecy is here described as a thing “too great” for Baruch. So also the fact that “her prophets did not find visions from the Lord” (Lam. 2:4), may be considered as the result of the exile of her prophets, as will be explained (chap. xxxvi.). There are, however, numerous passages in Scripture as well as in the writings of our Sages, which support the principle that it depends chiefly on the will of God who is to prophesy, and at what time; and that He only selects the best and the wisest. We hold that fools and ignorant people are unfit for this distinction. It is as impossible for any one of these to prophesy as it is for an ass or a frog; for prophecy is impossible without study and training; when these have created the possibility, then it depends on the will of God whether the possibility is to be turned into reality.
