הֵילִ֕ילוּ כִּ֥י קָר֖וֹב י֣וֹם יְהוָ֑ה כְּשֹׁ֖ד מִשַּׁדַּ֥י יָבֽוֹא׃
Howl ye; for the day of the LORD is at hand; As destruction from the Almighty shall it come.
Rashi on Isaiah
like a raid Like a day of plunder, from the Holy One, blessed be He, it shall come.
Ibn Ezra on Isaiah
משדי From the Almighty. This destruction shall come from the Almighty, and who shall be able to prevent it? According to others: From a destroying hero (שודד ═ שדי), but the former explanation is the right one.8The second explanation is rejected, probably because there is no instance of שדי being used in that sense.
