Genesis 1:14-19

Revised Standard Version Catholic Edition

¹⁴ And God said, “Let there be lights in the firmament of the heavens to separate the day from the night; and let them be for signs and for seasons and for days and years, ¹⁵ and let them be lights in the firmament of the heavens to give light upon the earth.” And it was so. 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. ¹⁹ And there was evening and there was morning, a fourth day.
