Kabbalah zu Ejchah 2:1

“the eyes of Hashem your Elohim are always upon it, from the beginning (reshit) of the year.” The word reshit is spelled without Aleph instead of customary spelling of reshit with Aleph. Who is called reshit without Aleph? It is lower Hei, namely, Malchut; reshit is derived from rash (poor). Of the higher it is written, “cast down from heaven to earth the beauty of Israel” (Eichah 2:1). What is the reason he “cast down from heaven (to) earth”?⁴4 Alternative reading: “he cast the earth from heaven” – translator that is, why was Malchut that is called earth cast down from Zeir Anpin that is called heaven? He answers, the reason lies the verse, “I clothe the heavens with blackness” (Yeshayahu 50:3), which means the eyes are black, namely, they were covered with the black color: when Malchut is separated from Zeir Anpin, having nothing to receive from him.
