Génesis 1

And he called the light, ‘Day,’ and the darknesses, ‘Night.’ And it became evening and morning, one day.

Y llamó Dios á la luz Día, y á las tinieblas llamó Noche: y fué la tarde y la mañana un día.

And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

God called the light “day”, and the darkness he called “night”. There was evening and there was morning, the first day.
