While the earth remaineth... — The traditional interpretation of this verse among the Jews represents the year as divided into six seasons. But this is untenable; for in Palestine itself there are two seed times, the winter crops being put into the ground in October and November, and the summer crops in January and February. Really the verse describes those great alternations upon which the well-being of the earth depends, whether considered absolutely, as of light and darkness, cold and heat, or with reference to man’s labours, as of sowing and harvesting; or relatively with respect to vegetation, winter being earth’s time of rest, and summer that of its activity.
