TSK · Isaiah 59:10

and you shall grope at noonday, as the blind gropes in darkness, and you shall not prosper in your ways: and you shall be only oppressed and robbed always, and there shall be none to save you.

The way of the wicked is like darkness. They don't know what they stumble over.

Give glory to Yahweh your God, before he causes darkness, and before your feet stumble on the dark mountains, and, while you look for light, he turns it into the shadow of death, and makes it gross darkness.

They wander as blind men in the streets, they are polluted with blood, So that men can't touch their garments.

Jesus answered, "Aren't there twelve hours of daylight? If a man walks in the day, he doesn't stumble, because he sees the light of this world.

"He has blinded their eyes and he hardened their heart, lest they should see with their eyes, and perceive with their heart, and would turn, and I would heal them."
