Genesis 1:16-18

Revised Standard Version Catholic Edition

¹⁶ And God made the two great lights, the greater light to rule the day, and the lesser light to rule the night; he made the stars also. ¹⁷ And God set them in the firmament of the heavens 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.
