And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars.
16. The greater light I have said, that Moses does not here subtilely descant, as a philosopher, on the secrets of nature, as may be seen in these words. First, he assigns a place in the expanse of heaven to the planets and stars; but astronomers make a distinction of spheres, and, at the same time, teach that the fixed stars have their proper place in the firmament.
This is the history of the fourth day's work, the creating of the sun, moon, and stars, which are here accounted for, not as they are in themselves and in their own nature, to satisfy the curious, but as they are in relation to this earth, to which they serve as lights; and this is enough to furnish us with matter for praise and thanksgiving.
Commenting on Genesis 1:14-19
And God made two great lights,.... This was his own work which he himself did, and not by another; and may be particularly observed to express the folly of idolaters in worshipping these luminaries which were the creations of God, and were placed by him in the heaven to serve some purposes on earth beneficial to men, but not to be worshipped.
