לְפָנָיו֙ רָ֣גְזָה אֶ֔רֶץ רָעֲשׁ֖וּ שָׁמָ֑יִם שֶׁ֤מֶשׁ וְיָרֵ֙חַ֙ קָדָ֔רוּ וְכוֹכָבִ֖ים אָסְפ֥וּ נָגְהָֽם׃
Diante deles a terra se abala; tremem os céus; o sol e a lua escurecem, e as estrelas retiram o seu resplendor.
Rashi on Joel
the heavens tremble—Because of the retribution coming upon Israel, they quake and tremble.
