And God said,
Let there be light:
and there was light.
All Commentaries on Genesis 1:3 Go To Genesis 1
Ephrem The Syrian
After Moses spoke of heaven and earth, of the darkness, the abyss and the wind that came to be at the beginning of the first night, he then turned to speak about the light that came to be at dawn of the first day. At the end of the twelve hours of that night, the light was created between the clouds and the waters and it chased away the shadow of the clouds that were overshadowing the waters and making them dark. For Nisan was the first month; in it the number of the hours of day and night were equal. The light, then, remained a length of twelve hours so that each day might also obtain its [ own ] hours just as the night possesses a measured length of time. Although the light and the clouds were created in the twinkling of an eye, the day and the night of the first day were each completed in twelve hours.
The light then was like a bright mist over the face of the earth. Whether it was like the dawn or like the pillar that gave light in the wilderness to the people, it is obvious that it was unable to chase away the darkness that was spread over the face of everything, unless it had spread out completely over everything, either by its substance or by its appearance. The light was released so that it might spread over everything without being fastened down. It dispersed the darkness that was over everything although it did not move. It was only when [ the light ] went away and when it came that it moved, so that when [ the light ] went away the rule was given to the night and at [ the light's ] coming there would be an end to [ the night's ] rule.
