כִּי֩ אֶת־הַבְּכֹ֨ר בֶּן־הַשְּׂנוּאָ֜ה יַכִּ֗יר לָ֤תֶת לוֹ֙ פִּ֣י שְׁנַ֔יִם בְּכֹ֥ל אֲשֶׁר־יִמָּצֵ֖א ל֑וֹ כִּי־הוּא֙ רֵאשִׁ֣ית אֹנ֔וֹ ל֖וֹ מִשְׁפַּ֥ט הַבְּכֹרָֽה׃ (ס)
반드시 그 미움을 받는 자의 아들을 장자로 인정하여 자기의 소유에서 그에게는 두 몫을 줄 것이니 그는 자기의 기력의 시작이라 장자의 권리가 그에게 있음이니라
Derech Etz Chayim (Ramchal)
...Behold, that goodness is in his hands and he controls the decision, whether to educate himself and understand or to remain naked of all wisdom, even though the heart and mind are contained within his body. It is readily apparent that there are two things created sharing similar functions: Man's intellect and and The Torah that imparts the intelligence.
