הָיִ֧יתִי בַיּ֛וֹם אֲכָלַ֥נִי חֹ֖רֶב וְקֶ֣רַח בַּלָּ֑יְלָה וַתִּדַּ֥ד שְׁנָתִ֖י מֵֽעֵינָֽי׃
Beginilah keadaanku: pada siang hari aku dimakan panas terik, dan pada malam hari oleh embun beku, sehingga tidur lenyap dari mataku.
Akeidat Yitzchak
(3) Light had to be the first of the ten directives to establish the beginning of coherent activity, since it removes a state of eternal darkness, stagnation etc. The term "day," which includes periods of darkness alternating with periods of light, provides the meaningful framework for all subsequent developments. This period of light would equal in duration the previous period of darkness. In this fashion, the two periods combined would constitute a "day." (4) Since the chronological sequence of events commenced with darkness followed by light, the order "it was evening, it was morning, one day" tells us that the term "day" comprises twenty-four hours divided into daylight and darkness. The statement, "one day" therefore describes the definition of "day," not how it ranks in the order of things. The division between light and darkness is natural, automatic, since one part of the globe is forever turned away from the sun, the source of light. An artificial act of separating light from darkness was therefore not necessary.
