וַיֹּאמֶר אֱלֹהִים

יְהִי מְאֹרֹת בִּרְקִיעַ הַשָּׁמַיִם

לְהַבְדִּיל בֵּין הַיּוֹם וּבֵין הַלָּיְלָה

וְהָיוּ לְאֹתֹת וּלְמוֹעֲדִים וּלְיָמִים וְשָׁנִים.

وَقَالَ اللهُ:

«لِتَكُنْ أَنْوَارٌ فِي جَلَدِ السَّمَاءِ

لِتَفْصِلَ بَيْنَ النَّهَارِ وَاللَّيْلِ

وَتَكُونَ لآيَاتٍ وَأَوْقَاتٍ وَأَيَّامٍ وَسِنِينٍ.

Y dijo Dios:

Sean lumbreras en la expansión de los cielos

para apartar el día y la noche:

y sean por señales, y para las estaciones, y para días y años;

And God said,

Let there be lights in the firmament of the heaven

to divide the day from the night;

and let them be for signs, and for seasons, and for days, and years:

Moses 2:14
And I, God, said: Let there be lights in the firmament of the heaven, to divide the day from the night, and let them be for signs, and for seasons, and for days, and for years;

Abraham 4:14
And the Gods organized the lights in the expanse of the heaven, and caused them to divide the day from the night; and organized them to be for signs and for seasons, and for days and for years;

Additional Notes/Questions:

At this point the chronology raises questions - because the previous verse refers to the growing of grasses, trees and other plant life, the day (or time period) before this one - where the lights were placed in the heavens. It would seem that, among other things, this order of creation might interfere just a bit with the normal process of photosynthesis.
