R’Yonatan said he saw and sat on the matzevah of a ben sorer umoreh.The question is how is it possible if the Tanna Kama said it will never happen? One answer is that he was referring to Avshalom who had a din of a ben sorer umoreh( according to the medrash) and R’Yonatan was explaining that this is what happens if one does not kill a ben sorer umoreh as a child.Another answer given is that the Tanna Kamma agrees that a child was killed, but it was a mistake because it was impossible for all the pratim of a ben sorer umoreh to happen all at once.(sefer Mrafsin igri). As a side note the word get(divorce document) is never mentioned in the Torah.Furthermore the letters of the word get, a gimmel and a tet never touch each other throughout the Torah because the essence of the word is to separate.(Vilna Gaon)
