The way of the wicked is as darkness: they know not at what they stumble.
1 Samuel 2:9
He will keep the feet of his saints, and the wicked shall be silent in darkness; for by strength shall no man prevail.
They meet with darkness in the daytime, and grope in the noonday as in the night.
They grope in the dark without light, and he maketh them to stagger like a drunken man.
Yea, the light of the wicked shall be put out, and the spark of his fire shall not shine.
The light shall be dark in his tabernacle, and his candle shall be put out with him.
He shall be driven from light into darkness, and chased out of the world.
Therefore is judgment far from us, neither doth justice overtake us: we wait for light, but behold obscurity; for brightness, but we walk in darkness.
We grope for the wall like the blind, and we grope as if we had no eyes: we stumble at noonday as in the night; we are in desolate places as dead men.
Give glory to the LORD your God, before he cause darkness, and before your feet stumble upon the dark mountains, and, while ye look for light, he turn it into the shadow of death, and make it gross darkness.
Wherefore their way shall be unto them as slippery ways in the darkness: they shall be driven on, and fall therein: for I will bring evil upon them, even the year of their visitation, saith the LORD.
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.
Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth.
1 John 2:11
But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.
