Genesis 1:14-16

14Then God said, “Let there be light-bearers (sun, moon, stars) in the expanse of the heavens to separate the day from the night, and let them be useful for signs (tokens) [of God’s provident care], and for marking seasons, days, and years;

15and let them be useful as lights in the expanse of the heavens to provide light on the earth”; and it was so, [just as He commanded].

16God made the two great lights—the greater light (the sun) to rule the day, and the lesser light (the moon) to rule the night; He made the [galaxies of] stars also [that is, all the amazing wonders in the heavens].
