וְשַׂמְתִּ֤י מִשְׁפָּט֙ לְקָ֔ו וּצְדָקָ֖ה לְמִשְׁקָ֑לֶת וְיָעָ֤ה בָרָד֙ מַחְסֵ֣ה כָזָ֔ב וְסֵ֥תֶר מַ֖יִם יִשְׁטֹֽפוּ׃
And I will make justice the line, And righteousness the plummet; And the hail shall sweep away the refuge of lies, And the waters shall overflow the hiding-place.
Read kabbalistic (mystical) interpretation of Isaiah 28:17: and classical mystical sources.
