'Darkness' in the Bible

the earth hath existed waste and void, and darkness is on the face of the deep, and the Spirit of God fluttering on the face of the waters,

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

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.

and to rule over day and over night, and to make a separation between the light and the darkness; and God seeth that it is good;

And the sun is about to go in, and deep sleep hath fallen upon Abram, and lo, a terror of great darkness is falling upon him;

And it cometh to pass -- the sun hath gone in, and thick darkness hath been -- and lo, a furnace of smoke, and a lamp of fire, which hath passed over between those pieces.
