דֶּ֤רֶךְ שָׁלוֹם֙ לֹ֣א יָדָ֔עוּ וְאֵ֥ין מִשְׁפָּ֖ט בְּמַעְגְּלוֹתָ֑ם נְתִיבֽוֹתֵיהֶם֙ עִקְּשׁ֣וּ לָהֶ֔ם כֹּ֚ל דֹּרֵ֣ךְ בָּ֔הּ לֹ֥א יָדַ֖ע שָׁלֽוֹם׃
The way of peace they know not, And there is no right in their goings; They have made them crooked paths, Whosoever goeth therein doth not know peace.
Read halakhic rulings (Jewish law) on Isaiah 59:8: and classical halakhic sources.
