What are "Ma'adanos Kimah"?
Rashi: They tie Kimah, lest all its cold go out and destroy the world. Malbim - Kimah is a group of stars in the north; cold comes from them.
Ibn Ezra #1: They are stars in the north; Kesil is in the south. Kimah ties Peros, which are Ma'adanos (delicacies); Kesil does the opposite.
Ibn Ezra citing early astronomers: They are seven small stars at the end of Mazal Tleh; six of them are visible.
Ibn Ezra #2: I say that it is one big star - the left eye of Shor. Kimah is a big star - the heart of Akrav. When both of these rise in the east, the mentioned deeds are seen.
What was the question "Haskasher Ma'adanos Kimah"?
Ibn Ezra: Did you command these stars to tie and open?
Malbim: Did you command Kimah to freeze water, [or Kesil to open the binds and melt ice]?
Why does He open the ropes of Kesil?
Rashi: It is to let out its heat, to blunt the chill from Kimah. Malbim - Kesil is a group of stars in the south; heat comes from them.
