Thomas Aquinas

“ Nevertheless teaching was commanded more expressly than learning, because it concerned the learned, who were not under any other authority, but were immediately under the law, and to them the precepts of the Law were given. On the other hand learning concerned the people of lower degree, and these the precepts of the Law have to reach through the learned. ”

“ For knowledge and understanding pertain to cognition. Now cognition precedes and directs action. Therefore the precepts referring to knowledge and understanding should precede the precepts of the Law referring to action. Since, then, the first precepts of the Law are those of the decalogue, it seems that precepts of knowledge and understanding should have been given a place among the precepts of the decalogue.
Objection 2: Further, learning precedes teaching, for a man must learn from another before he teaches another. ”

“ Now the Old Law contains precepts about teaching---both affirmative precepts as, for example, (Dt. 4:9) , "Thou shalt teach them to thy sons"---and prohibitive precepts, as, for instance, (Dt. 4:2) , "You shall not add to the word that I speak to you, neither shall you take away from it." Therefore it seems that man ought to have been given also some precepts directing him to learn. ”
