창세기 1:4의 주석

וירא אלהים את האור כי טוב ויבדל AND GOD SAW THE LIGHT THAT IT WAS GOOD, AND GOD CAUSED A DIVISION — Here, also, we must depend upon the statement of the Agada: He saw that the wicked were unworthy of using it (the light); He, therefore, set it apart (ויבדל), reserving it for the righteous in the world to come (Chagigah 12a). But according to the plain sense explain it thus: He saw that it was good, and that it was not seemly that light and darkness should function together in a confused manner. He therefore limited this one’s sphere of activity to the daytime, and this one’s sphere of activity to the nighttime (see Genesis Rabbah 3:6).

וירא אלוקים את האור, He looked at its appearance and it was good. The statement is similar to Yocheved saying ותרא אותו כי טוב, (Exodus 2,2) although he had been born three months prematurely, just as had Samuel. In practice, the fact that all his vital features including the nails of his toes and fingers and the hairs on his head had grown, gave her the feeling that he was “good,” i.e. a viable human being, so that she proceeded to hide him for three months because she knew that he was not premature in the sense of not being viable.

וירא אלוקים את האור כי טוב, This describes the reason why G’d created the light, not that He “saw”” something new which He had not been aware of previously. It was because it was “good,” that G’d had created the light.
