창세기 44:12 탈무드 참조: Pesachim

This light of the sun, where is it meant? Shall we say, in a courtyard, — but Raba said: A courtyard does not require searching, because birds frequent it. While if in a hall, but Raba said: A hall is searched by its own light? — This is meant only in respect of a skylight in a room. But [then] what part of it? If [that which is] opposite the skylight, then it is the same as a hall? — Rather, it means [the part of the room] at the sides. And not [by the light of] a torch? Surely Raba said, What is the meaning of the verse, "And his brightness was as the light; he had rays coming forth from his hand: and there was hiding of his power?" To what are the righteous comparable in the presence of the Shechinah? To a lamp in the presence of a torch. And Raba also said: [To use] a torch for havdalah is the most preferable [way of performing this] duty? — Said R. Nahman b. Isaac: The one can be brought into holes and chinks [in the wall], whereas the other cannot be brought into holes and chinks. R. Zebid said: The one [throws] its light forward, whereas the other [throws] its light behind. R. Papa said: Here [with a torch] one is afraid, whereas there [with a lamp] one is not afraid. Rabina said: The light of the one is steady, whereas that of the other is fitful.
