The Gemara (חולין ט, א) declares that a Talmid Chacham must know three things: ksav (writing), shechitah, and milah. Rashi (ד"ה כתב) explains that "ksav" means the simple knowledge of writing, for the scholar should know how to sign his name were he to sit as a judge or a witness.
Explaining why it doesn't mean the knowledge of the laws of writing a Sefer Torah etc., the Maharsh"a explains that the Torah scholar's knowledge of all areas of halachah is a given; this cannnot be what the Gemara means when it says that he must be knowledgeable in "writing." Rather, the intent is the skill of signing his name.
Alternatively, the intent is the obligation a Talmid Chacham has to "transcribe" his Torah thoughts. One whom Hashem has bestowed with the wisdom to expand Torah knowledge is obligated to do so lest it be forgotten. Should he not do so, it is tantamount to spilling seed in vain.

If the laws of Sefer Torah are a given, why isn't Shchitah and Milah a given?
ReplyDeleteEli - good question! Look at the Maharsh"a who explains further that this is why Rashi indeed doesn't learn the Gemara to be referring to the LAWS of shechitah and milah, but rather the MOTOR SKILLS that these practice require.
