לְעֵ֥ת עֶ֙רֶב֙ וְהִנֵּ֣ה בַלָּהָ֔ה בְּטֶ֥רֶם בֹּ֖קֶר אֵינֶ֑נּוּ זֶ֚ה חֵ֣לֶק שׁוֹסֵ֔ינוּ וְגוֹרָ֖ל לְבֹזְזֵֽינוּ׃ (ס)
At eventide behold terror; And before the morning they are not. This is the portion of them that spoil us, And the lot of them that rob us.
Read halakhic rulings (Jewish law) on Isaiah 17:14: and classical halakhic sources.
