Tafsiran Yesaya 50:3: Rashi, Ibn Ezra & Tze'enah Ure'enah

I clothe the heavens The host of the heavens, the princes of the heathens (nations [Mss. and K’li Paz]), when I come to mete out retribution upon the nations.

מלבוש קדרׂות ═ קדרות With black cloth,²A. V., With blackness. See c. xlix. Note 23. that is, with clouds. Some understand it to refer to an eclipse of the sun, when the sky becomes obscure in the middle of the day, and appears as if covered with sackcloth, which is usually black.

“I clothe the skies in blackness and make their raiment sackcloth” [50:3]. The Holy One said: I have done even more in Egypt. I clothed the skies in black. That is to say, I caused three days of darkness in Egypt. And sackcloth over heaven. That is to say, they should not shine and therefore see that I can perform wonders. How could you think that I could not take you out of the exile?¹⁰Radak, Isaiah, 50:3.
