אִם־יֶחֱטָ֨א אִ֤ישׁ לְאִישׁ֙ וּפִֽלְל֣וֹ אֱלֹהִ֔ים וְאִ֤ם לַֽיהוָה֙ יֶֽחֱטָא־אִ֔ישׁ מִ֖י יִתְפַּלֶּל־ל֑וֹ וְלֹ֤א יִשְׁמְעוּ֙ לְק֣וֹל אֲבִיהֶ֔ם כִּֽי־חָפֵ֥ץ יְהוָ֖ה לַהֲמִיתָֽם׃
If one man sin against another, God shall judge him; but if a man sin against the LORD, who shall entreat for him?’ But they hearkened not unto the voice of their father, because the LORD would slay them.
Rabbeinu Bahya
