Genesis 1:16-18

New Revised Standard Version Catholic Edition

¹⁶ God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. ¹⁷ God set them in the dome of the sky to give light upon the earth, ¹⁸ to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good.
