Hisgalus 9:1-2

Orthodox Jewish Bible

9 And the malach hachamishi (fifth angel) sounded his shofar; and I saw a kokhav (star) having fallen out of Shomayim to ha’aretz. And was given to it the mafte’ach (key) of the shaft of the Tehom (Abyss).

² And he opened the shaft of the Tehom (Abyss), and smoke came up out of the shaft as smoke of a great furnace, and the shemesh (sun) was darkened and the air was darkened by the smoke of the shaft. [BERESHIS 19:28; SHEMOT 19:18; YOEL 2:2,10]
