Chasidut for Yoma 70:11

ויהי בימים וגו' וירא בסבלותם: In the Medrash it is written that G-d saw that they had no rest, and Moshe went and established the Shabbat day. This needs explanation - how is it hinted to here that Moshe established the day of rest for them? The verse says that G-d saw their hardships, no more no less. However, there is undoubtedly a hint towards the Shabbat day. The idea is that in every element of the creation of the world the words וירא אלהים כי טוב are used. How is it possible for the verse to say that G-d saw - didn't he see before/during his creation of the world? However, the intention of the verse is that through G-d's vision he was able to put the light (that he had created in the first day) into them. The only time it doesn't say כי טוב is when G-d created darkness and תוהו ובהו on the first day, and on the second day, G-d created Gehinom according to the Talmud in Pesachim (54A). The verse that says that G-d created evil, even though such a concept is not mentioned in the Genesis account of the creation of the world.
