וַיְהִי־ק֕וֹל מֵעַ֕ל לָרָקִ֖יעַ אֲשֶׁ֣ר עַל־רֹאשָׁ֑ם בְּעָמְדָ֖ם תְּרַפֶּ֥ינָה כַנְפֵיהֶֽן׃
For, when there was a voice above the firmament that was over their heads, as they stood, they let down their wings.
Rashi on Ezekiel
And there was a voice above the expanse Jonathan rendered: And at the time that there was a will before Him to make His speech heard to His servantsthe prophets of Israelthere was a voice, and it was heard from above the expanse, from between the cherubim, from beneath the expanse that was over their heads.
Rashi on Ezekiel
they would let down their wings out of the fear of the speech.
