'Darkness' in the Bible

the people who sit in darkness have seen a great light, and on those who sit in the region and shadow of death a light has dawned."

But if your eye is diseased, your whole body will be full of darkness. If then the light in you is darkness, how great is the darkness!

but the sons of the kingdom will be thrown out into the outer darkness, where there will be weeping and gnashing of teeth."

Then the king said to his attendants, 'Tie him up hand and foot and throw him into the outer darkness, where there will be weeping and gnashing of teeth!'

And throw that worthless slave into the outer darkness, where there will be weeping and gnashing of teeth.'

Now from noon until three, darkness came over all the land.
