The eclipsed relationship[1]
ויאמר אלקים יהי מארת ברקיע השמים להבדיל בין היום ובין הלילה והיו לאתת ולמועדים ולימים ושנים
G-d said: “Let there be luminaries in the sky to separate between day and night, and they will be for signs, set times, days and years”[2]
On the fourth day of Hashem’s Six Days of Creation, we are taught that Hashem created what we know today as the Sun and the Moon. These celestial bodies, besides their other purposes, serve as practical time indicators. They’re used to distinguish between day and night, and to tell how far along it is during the day and night. As well, the Jewish Calendar is set up to rely on the lunar cycle, and the stage the Moon is in indicates how far along it is in the month. Many festivals occur during the full Moon, and the New Moon indicates the start of a new month. The Torah says that the luminaries are also for “signs”. What signs is the Torah referring to?
