Genesis 1:19-21

19 And the evening and the morning were the fourth day.

20 And God said, Let the waters swarm [with] swarmers [having] a living soul; and let birds fly over the earth on the face of the expanse of the heavens.

21 And God created great sea-animals, and every living soul that creeps [with] which the waters swarmed after their kind; and every winged fowl after its kind. And God saw that [it was] good.
