וַיַּ֧רְא אֱלֹהִ֛ים אֶת־הָא֖וֹר כִּי־ט֑וֹב וַיַּבְדֵּ֣ל אֱלֹהִ֔ים בֵּ֥ין הָא֖וֹר וּבֵ֥ין הַחֹֽשֶׁךְ׃
Y vió Dios que la luz era buena: y apartó Dios la luz de las tinieblas.
Zohar
“in the sight of the sons of men”, inasmuch as it is the functioning of this light that makes possible the existence of mankind, who are sustained by it despite the fact that the light itself is stored away. Again, “which thou hast wrought”, viz. as a medium for the construction of the world according to an orderly plan;
Zohar
"And God said: 'Let there be lights in the firmament of heaven.'" [Bereshit 1:14]. Male having power over Female, as it is written: "And the righteous is the foundation of the world." [Proverbs 10:25]. Yod (י) illumines two, and illumines and impregnates the Female. Yod (י) is unified by itself (and after this) it ascends on its rungs higher and higher. The Female is darkened, and the Mother is illumined and is being opened by her gates. A key has come that consists of six, and it covers her opening, and closes/links downward this one and that one. Woe to the one who reveals her opening.
Zohar Chadash
"And God saw the light, it was good;" What was it that He saw, that was good? Rabbi Hiyya said that this implies that He foresaw the actions of the wicked, and still stored the light, for reasons we've said before. But, Rabbi Aba says, "And God saw the light, it was good;" because it was good to hide. He saw its radiance beaming from one end of the world to the other, and He saw that it was better to conceal it, so that sinners might not benefit from it. Rabbi Shimon said that no anger or judgement may be found in "And God saw the light, it was good;" After all, it is written, "Balaam saw that it pleased the Lord to bless Israel" (Num. 24:1) and this is proven by the verse's closing, "And God divided the light from the darkness" (Gen. 1:4), to snuff wrath, even though the Holy One, Blessed be He, later (re-)combined the two.
