Vulgate: Genesis Chapter 1
In principio creavit Deus cælum et terram.
In the beginning God created the heaven(s) and the earth.
Terra autem erat inanis et vacua, et tenebræ erant super faciem abyssi: et spiritus Dei ferebatur super aquas.
Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
Dixitque Deus: Fiat lux. Et facta est lux.
And God said, “Let there be light,” and there was light.
dixit+que = And, (God) said
Fiat = Fiat is the jussive subjunctive form of the verb facio (to make, to build, sometimes to be).
