'Walks in Darkness' in the Bible

The wise man has eyes in his head,but the fool walks in darkness.Yet I also knew that one fate comes to them both.

Who among you fears the Lord,listening to the voice of His Servant?Who among you walks in darkness,and has no light?Let him trust in the name of Yahweh;let him lean on his God.

Jesus answered, “The light will be with you only a little longer. Walk while you have the light so that darkness doesn’t overtake you. The one who walks in darkness doesn’t know where he’s going.
