And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
All Commentaries on Genesis 1:16 Go To Genesis 1
Ephrem The Syrian
AD 373
Indeed Moses said, "God made the two great lights, the greater light to rule the day, and the lesser light to rule the night; and [ He made ] the stars." [ Gen1:16 ] Although all that was done before the fourth day was begun in the evening, the works on the fourth day were fashioned at dawn. Because the third day had been completed, in that it is said, "It was evening and it was morning; day three," God did not create the two lights in the evening lest night be changed into day and morning be given priority over evening.
Because the days followed the same order in which the first day was created, the night of the fourth day, like that of the other days, preceded its day. And if its evening preceded its dawn, the lights were not created in the evening, but rather at dawn. But to say that one of them was created in the evening and the other at dawn cannot be allowed for Moses said, "Let there be lights," and "God made the two great lights." If they were great when they were created and they were created at dawn, then the sun would have stood in the east and the moon opposite it in the west. The sun would have been set very low because it was created in the place where it set out over the earth, whereas the moon would have been set higher because it was created in the place where it stands on the fifteenth day. Indeed, at the moment the sun appears over the earth, the lights see each other and then the moon sinks. From the position of the moon, from its size and from the light it produced, it is clear, then, that it was fifteen days old when it was created.
Just as the trees, the vegetation, the beasts, the birds and even mankind were old, so were they also young. They were old according to the appearance of their limbs and their substances, yet they were young because of the hour and moment of their creation. Likewise, the moon was both old and young. It was young, for it was but a moment old, but was also old, for it was full as it is on the fifteenth day.
If the moon had been created a day old or even two, it would have given no light; because of its proximity to the sun, it would not even have been visible. If it had been created about four days old, although it might have been visible, it would still not have given any light. This would have rendered false the verse "God created the two great lights," as well as "He said, 'Let there be lights in heaven to give light upon the earth.'" Therefore, the moon had to be fifteen days old. The sun, although it was only one day old, was nevertheless four days old, for it is according to the sun that each day was counted and will be reckoned. Accordingly, those eleven days that were added to the moon at that first moment, by which the moon was older than the sun, are also added to it each year, for these [ days ] are used in the lunar reckoning.
There was nothing lacking in that year for Adam and his descendants, for any deficiency in the measure of the moon had been filled in when the moon was created. Thus, Adam and his descendants learned from this year that, henceforth, eleven days were to be added to every year. Clearly then, it was not the Chaldeans who arranged the times and years; these things had been arranged before [ the creation of ] Adam.
