פירוש על שבת 46:4

Children who are Torah scholars: As it is written (Proverbs 6:23), "For the commandment is a lamp; and Torah is light" - through the lamp of the commandment of Shabbat and Channukah, comes the light of Torah.

This is the version we teach, "He saw that they were accustomed to lights": The explanation is both the husband and wife [were accustomed to this]. Hence he said, "Two great men will emerge from here." And later, it said [that] he saw that only the wife was accustomed [to it]. Hence he said, "A great man will emerge from here," in her merit.

Of Rabbi Avin Nagra: [Nagra means] a cutter of wood.

In Rabbi Sheivzi's family's house (bei nasha): Rabbenu Tam said that [R. Sheizvi]'s father had already died. Hence it said it with this expression. As if he was alive, it should have said, "in his father's house." And Rabbenu Tam said in the name of Rabbi Shmuel that when we write a marriage contract (ketuvah) - if the father of the bride is alive, we write, "that she brings to him from her father's house." But if he is already dead, we write, "that she brings to him from her family's house." However, it appears to Rashba that we find that even when he is alive, it says, "the family's house": In the chapter [entitled] Mi SheHechshikh (Shabbat 156a) - "Levi, son of Rav Huna bar Chiyah, found the one who kneads in his family's home kneading bran and feeding it to his ox. He kicked him. His father came and found him." So he can write what he wants on the marriage contract.

With light of Shabbat.

Exchange and teach: Pass by and teach, meaning to say he would always pass by.

In the family's house: [Of] his father; and some say, his father-in-law.

Emerged from them: For his son-in-law is like his son.
