Genesis 1:19-21

Revised Standard Version Catholic Edition

¹⁹ And there was evening and there was morning, a fourth day.

²⁰ And God said, “Let the waters bring forth swarms of living creatures, and let birds fly above the earth across the firmament of the heavens.” ²¹ So God created the great sea monsters and every living creature that moves, with which the waters swarm, according to their kinds, and every winged bird according to its kind. And God saw that it was good.
