욥기 38:12의 주석

In [all] your days From the day you were born.

Of all natural phenomena none is more central nor wondrous than light. However, as with water, Providence can alter its nature too as circumstances require. Has Job any such power over it?
From the moment the sun and moon were put into position on the fourth day of Creation, the cycle of day and night as we now know it began. In this cycle, daybreak is a shadowy line of longitude that moves continuously across the face of the Earth from east to west with a period of 24 hours. God asks Job if he knows from where that line started to move on the fourth day of Creation.
Have you ever called up the morn?... This refers to the first morning of Creation. According to Malbim, during each of the first three days of Creation, i.e., before the sun and moon were placed in position, there was light over the entire planet Earth for 12 hours followed by 12 hours of darkness everywhere. The change from light to dark and back again was gradual, such that 'evening came and morning came' (Genesis 1:5).
