Genesis 1:4-6

4 And God seeth the light that [it is] good, and God separateth between the light and the darkness,

5 and God calleth to the light ‘Day,’ and to the darkness He hath called ‘Night;’ and there is an evening, and there is a morning — day one.

6 And God saith, ‘Let an expanse be in the midst of the waters, and let it be separating between waters and waters.’
