הַעִידֹ֨תִי בָכֶ֣ם הַיּוֹם֮ אֶת־הַשָּׁמַ֣יִם וְאֶת־הָאָרֶץ֒ הַחַיִּ֤ים וְהַמָּ֙וֶת֙ נָתַ֣תִּי לְפָנֶ֔יךָ הַבְּרָכָ֖ה וְהַקְּלָלָ֑ה וּבָֽחַרְתָּ֙ בַּֽחַיִּ֔ים לְמַ֥עַן תִּחְיֶ֖ה אַתָּ֥ה וְזַרְעֶֽךָ׃
I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse; therefore choose life, that thou mayest live, thou and thy seed;
Zohar
Come and see how twisted we are, human beings, that we do not want to follow the ways of life that the Holy One of Blessing has taught us, God's children, the God warned us and said "and meditate upon this day and night" (Joshua 1:8) - we don't have the permission to split day from night. And so too with Yehudah, even though he separated himself and worked in the West which is [called] Night, the rest of the travels of his tents were turned to the East, which is [called] Day. And the Holy One of Blessing indicated it to him, and said "and you shall choose life" (Deut. 30:19), meaning, he should not split day from night, and a person who does so brings about death.
