וּבָ֙אוּ֙ בִּמְעָר֣וֹת צֻרִ֔ים וּבִמְחִלּ֖וֹת עָפָ֑ר מִפְּנֵ֞י פַּ֤חַד יְהוָה֙ וּמֵהֲדַ֣ר גְּאוֹנ֔וֹ בְּקוּמ֖וֹ לַעֲרֹ֥ץ הָאָֽרֶץ׃
Targum Jonathan on Isaiah
And they shall go into the caves of the rocks, and into the caverns of the earth, for the fear of the Lord, and for the brightness of His glory, when He shall be revealed to destroy the wicked of the earth.
