וַיֵּ֥ט שָׁמַ֖יִם וַיֵּרַ֑ד וַעֲרָפֶ֖ל תַּ֥חַת רַגְלָֽיו׃
He bowed the heavens also, and came down; and thick darkness was under His feet.
Rashi on II Samuel
He bent heaven. To take revenge from His enemies, from Mitzrayim and from Pharoah.
וַיֵּ֥ט שָׁמַ֖יִם וַיֵּרַ֑ד וַעֲרָפֶ֖ל תַּ֥חַת רַגְלָֽיו׃
He bowed the heavens also, and came down; and thick darkness was under His feet.
