네가 호렙 산에서 네 하나님 여호와 앞에 섰던 날에 여호와께서 내게 이르시기를 나를 위하여 백성을 모으라 내가 그들에게 내 말을 들려서 그들로 세상에 사는 날 동안 나 경외함을 배우게 하며 그 자녀에게 가르치게 하려 하노라 하시매

And, in truth, the expenditures for the Torah study of his sons are outside of the expenditures for sustenance fixed for him on Rosh Hashanah, as Chazal have said (Beitzah 16a): "All the sustenance for man is fixed for him from Rosh Hashanah until Yom Kippur, except expenditures for Shabbath, …and expenditures for his sons' Torah studies, which, if he gives less, he is given less [by Heaven], and if he gives more, he is given more." Come and see what Chazal have said (Kiddushin 30a): "If one teaches his son's son Torah, Scripture reckons it unto him as if he had received it on Mount Sinai, viz. Devarim 4:9: 'And you shall impart them [(words of Torah)] to your sons and to the sons of your sons," followed by (Ibid. 10): 'the day you stood before the L-rd your G-d in Chorev.'" Also, through this, he merits long life for him and his sons, it being written (Ibid. 11:19): "And you shall teach them to your sons," followed by (Ibid. 21): "So that your days be prolonged and the days of your sons, etc."
