Torah is not Inherited

 Nedarim (81a) Be on guard against scabs; take good care to study in company and be heedful not to neglect the children of the poor, for from them Torah goeth forth, as it is written, The water shall flow out of his buckets meaning, from the poor amongst them goeth forth Torah. And why is it not usual for scholars to give birth to sons who are scholars? — Said R. Joseph, That it might not be maintained, The Torah is their legacy. R. Shisha, the son of R. Idi, said: That they should not be arrogant towards the community. Mar Zutra said: Because they act high-handedly against the community. R. Ashi said: Because they call people asses. Rabina said: Because they do not first utter a blessing over the Torah. For Rab Judah said in Rab's name: What is meant by, Who is the wise man, that he may understand this. . . for what is the land destroyed etc.? Now, this question was put to the Sages, Prophets, and Ministering Angels, but they could not answer it, until the Almighty Himself did so, as it is written, And the Lord said, Because they have forsaken my law which I set before them, and have not obeyed my voice, neither walked therein: but is not ‘have not obeyed my voice’ identical with, ‘neither walked therein’? — Rab Judah said in Rab's name: It means that they did not first recite a benediction over the Torah.
