עַל־כֵּ֗ן מָלְא֤וּ מָתְנַי֙ חַלְחָלָ֔ה צִירִ֣ים אֲחָז֔וּנִי כְּצִירֵ֖י יֽוֹלֵדָ֑ה נַעֲוֵ֣יתִי מִשְּׁמֹ֔עַ נִבְהַ֖לְתִּי מֵרְאֽוֹת׃
Therefore are my loins filled with convulsion; Pangs have taken hold upon me, as the pangs of a woman in travail; I am bent so that I cannot hear; I am affrighted so that I cannot see.
Read kabbalistic (mystical) interpretation of Isaiah 21:3: and classical mystical sources.
