To the law and to the testimony: if they speak not according to this word, {it is} because {there is} no light in them. {no...: Heb. no morning}
Modern English
Turn to the law and to the testimony! If they don’t speak according to this word, surely there is no morning for them.
Hebrew
לְתוֹרָ֖ה וְלִתְעוּדָ֑ה אִם־לֹ֤א יֹֽאמְרוּ֙ כַּדָּבָ֣ר הַזֶּ֔ה אֲשֶׁ֥ר אֵֽין־ל֖וֹ שָֽׁחַר׃
