וְאֶל־מְצ֤וֹר יְרוּשָׁלִַ֙ם֙ תָּכִ֣ין פָּנֶ֔יךָ וּֽזְרֹעֲךָ֖ חֲשׂוּפָ֑ה וְנִבֵּאתָ֖ עָלֶֽיהָ׃
At sa pagkubkob sa Jerusalem mo itutuon ang iyong mukha, nakalantad ang iyong bisig, at ikaw ay manghuhula laban dito.
Rashbam
מחשוף, exposed, visible. Compare the same expression in Ezekiel 4,7, or in Isaiah 52,10 חשף ה' את זרוע קדשו, “the Lord bared His holy arm.”
