" Divided the light from the darkness..."
" And this earth was once confused and tangled, and darkness was over the turmoil, and the breath of G-d hovered above the waters. Then G-d spake : Let there be light ! And there was light.
And G-d saw the light that it was good, and G-d divided the light from the darkness:
And G-d called to the light : Day...! and to the darkness He called : Night...! and it became evening and it became morning : one day. "
