וְהָיָ֖ה מֵהַנַּ֣חַל תִּשְׁתֶּ֑ה וְאֶת־הָעֹרְבִ֣ים צִוִּ֔יתִי לְכַלְכֶּלְךָ֖ שָֽׁם׃
Tu boiras de ses eaux, et les corbeaux, sur mon ordre, y pourvoiront à tes besoins."
Radak
ויכלו השמים והארץ וכל צבאם, this verse refers to both the hosts of heaven and the hosts of earth, including their respective derivatives, תולדותם. They had all been completed on the sixth “day,” and henceforth there would not be any new phenomena in the universe, unless created by a special act of miracle. The fact is, that already during the first six “days” when the laws of nature were formulated by the Creator, He inserted escape clauses into this system of natural law that would allow Him, if and when required, to temporarily suspend such laws at His discretion.
This is explained in Bereshit Rabbah 5,5 where Rabbi Yochanan (or Yonathan) is quoted as saying that G’d entered into an agreement with the oceans that when the time would come they would respond to Moses’ command to be split, etc., in order for the Israelites at that time to cross on dry land. This is the meaning of the words in Exodus 14,26 וישב הים לפנות בוקר לאיתנו, “the sea returned towards morning to its original format.” This is a reference to the condition which G’d had imposed on the sea at the time He set certain rules for it to follow. Rabbi Yirmiyah ben Eliezer added that G’d had not only made such arrangements with the oceans, but also with all other phenomena which He had created during those six “days;” this is reflected by Isaiah 45,12אני, ידי נטו שמים וכל צבאם צויתי, “My own hands stretched out the heavens and I marshaled their host.” The extra word צויתי, refers to this clause. We also have Joshua 10,13 in which Joshua is described as arresting the sun and the moon in their respective orbits. Had it not been for the provision by G’d at the time of the creation of these planets, Joshua could not have successfully ordered them to perform what would have been an act of disobedience against the rules set for them by G’d. The same holds true for G’d’s dispatching the ravens to feed meat to the prophet Elijah (Kings I 17,4-6), or His ordering the fire not to burn Chananyah, Mishael and Azaryah. (Daniel 3,23) G’d had also ordered the lions not to harm Daniel (Daniel 6,26). Similarly, G’d had commanded the whale to swallow Jonah, keep him alive, etc. (Jonah 2,11)

Tze'enah Ure'enah
“And he sent out the raven” [8:7]. Noah sent the raven to see if the water had decreased and the raven did not want to go. It said: the Holy One hates me. The Holy One said to take seven of the clean birds into the ark and of me, the Holy One said to take one pair, my female and me, and now you want to send me from the ark. Perhaps I will be killed and how will my species exist in the world? The raven said to Noah: you want to have relations with my wife and that is why you are sending me away from the ark. Noah responded: you evildoer, I have not slept with my wife a whole year because we are in the ark, so how do you want to say that I want to sleep with your female? Noah did not want to let him back in. You are not worthy to be eaten and more so as a sacrifice. The Holy One said: let him in, he is prepared for a mission. In the days of Elijah the prophet, when Elijah was hidden because of king Ahab, and Elijah did not have food to eat, the ravens brought meat and bread from the house of Ahab to Elijah where he lay in hiding.41Bahya, Genesis, 8:7. The Elijah reference is found in I Kings 17:4–6.
