לָכֵ֗ן כֹּ֚ה אָמַ֣ר יְהוָ֔ה הִנְנִ֥י נֹתֵ֛ן אֶל־הָעָ֥ם הַזֶּ֖ה מִכְשֹׁלִ֑ים וְכָ֣שְׁלוּ בָ֠ם אָב֨וֹת וּבָנִ֥ים יַחְדָּ֛ו שָׁכֵ֥ן וְרֵע֖וֹ יאבדו [וְאָבָֽדוּ׃] (פ)
Therefore thus saith the LORD: Behold, I will lay stumblingblocks before this people, And the fathers and the sons together shall stumble against them, The neighbour and his friend, and they shall perish.
