Talmud su Genesi 1:4

“Also, one does not recite the benediction over a lamp unless one has profited from its light.¹⁵⁰Quote from the Mishnah.” Rebbi Zeïra, the son of Rebbi Abbahu, preached: (Gen. 1:4) “God saw the light that it was good” and after that, “God separated between the light and the darkness.¹⁵³In imitatio Dei, one should not make Havdalah until he saw the light and that it is useful. The same paragraph is found in Bereshit rabba3(7) in slightly more explicit language.”. Rebbi Berekhiah said: The following was preached by the two greats of the world, Rebbi Yoḥanan and Rebbi Simeon ben Laqish: “God separated,” a true separation. Rebbi Yehudah, the son of Rebbi Simon, said: He separated it for Himself¹⁵⁴That this is the light of the Shekhinah.. But the rabbis say, He separated it for the just in the future world. They gave a parable, to what can this situation be compared? To a king who had two generals¹⁵⁵Greek (sing.) στρατηγός.; both of them said: “I want to command during the day.” He called the first one and told him: day shall be your domain. He called the second one and told him: night shall be your domain. That is what is written: (Gen. 1:5) “God called the light ‘day’, etc.” To the light he said: day shall be your domain; but to the darkness he said: night shall be your domain. Rebbi Yoḥanan said, that it is which the Holy One, praise to Him, said to Job: (Job 38:12) “Did you ever command the morning, did you inform the morning of its place?” Do you know the place where the light of the Six Days of Creation was hidden? Rebbi Tanḥuma said: I shall give its reason. (Is. 45:7) “He Who fashioned the light and created darkness, He makes peace.” When it left¹⁵⁶In Bereshit rabba: “From the moment that they were created, He is making peace.”, it made peace between them.
