Then God said, Let there be light! And the light came. And God saw the light, and it pleased him, and he gave it the name of Day. And when the day was gone, and the dark came back to stay for a while, he gave the dark spell the name of Night. And God did these things on the first day.

— Josephine Pollard, History of the Old Testament in Words of One Syllable, 1888
