לָכֵ֗ן יִֽהְיֶ֤ה לָכֶם֙ הֶעָוֺ֣ן הַזֶּ֔ה כְּפֶ֣רֶץ נֹפֵ֔ל נִבְעֶ֖ה בְּחוֹמָ֣ה נִשְׂגָּבָ֑ה אֲשֶׁר־פִּתְאֹ֥ם לְפֶ֖תַע יָב֥וֹא שִׁבְרָֽהּ׃
Therefore this iniquity shall be to you as a breach ready to fall, swelling out in a high wall, whose breaking cometh suddenly at an instant.
Read kabbalistic (mystical) interpretation of Isaiah 30:13: and classical mystical sources.
