'Darkness' in the Bible

to shine on those who sit in darkness and in death's shadow, and to guide our feet into the way of peace."

Your eye is the lamp of your body. When your eye is healthy, your whole body is full of light. But when it's evil, your body is full of darkness.

Therefore, be careful that the light in you isn't darkness.

Now if your whole body is full of light, with no part of it in darkness, it will be as full of light as when a lamp gives you light with its rays."

Therefore, what you have said in darkness will be heard in the daylight, and what you have whispered in private rooms will be shouted from the housetops."

While I was with you day after day in the Temple, you didn't lay a hand on me. But this is your hour, when darkness reigns!"
