And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years. Genesis 1:14
These and the stars represent one huge universal clock, they represent time. The sun representing the big hand and the moon representing the small hand & the stars representing the minutes.
1. The sun = The days
2. The moon = The months
3. The stars = The seasons
These two great lights & the stars circuit the heavens.
It rises at one end of the heavens and runs it's circuit to the other. Psalms 19:6
God who created the universe according to the laws of physics and set it in motion like a well-made clock.
All these he set in the firmament.
And God set them in the firmament of the heaven to give light upon the earth, Genesis 1:17
