מִדֵּ֤י עָבְרוֹ֙ יִקַּ֣ח אֶתְכֶ֔ם כִּֽי־בַבֹּ֧קֶר בַּבֹּ֛קֶר יַעֲבֹ֖ר בַּיּ֣וֹם וּבַלָּ֑יְלָה וְהָיָ֥ה רַק־זְוָעָ֖ה הָבִ֥ין שְׁמוּעָֽה׃
As often as it passeth through, it shall take you; For morning by morning shall it pass through, By day and by night; And it shall be sheer terror to understand the message.
Read halakhic rulings (Jewish law) on Isaiah 28:19: and classical halakhic sources.
