Note 47 — Chapter VI · LIGHT AND CREATIVE DAYS. "And God said, Let light be, and light was; and God saw the light that it was good, and separated the light from the darkness; and God called the light Day; and the darkness he called Night. And Evening was and Morning was—Day one."— Genesis i., 3-5.
Reading edition
Professor Dana thus sums up the various meanings of the word day in Genesis: "First, in verse 5, the light in general is called day, the darkness night. Second, in the same verse, evening and morning make the first day, before the sun appears. Third, in verse 14, day stands for twelve hours, or the period of daylight, as dependent on the sun. Fourth, same verse, in the phrase "days and seasons," day stands for a period of twenty-four hours. Fifth, at the close of the account, in verse 4 of the second chapter, day means the whole period of creation. These uses are the same that we have in our own language." Warring, in his book "The Miracle of To-day," has suggested that the Mosaic days are epochal days, each considered as the close and culmination of a period. This is an ingenious suggestion, and very well coincides with the day-period theory as defended in the text.
