'Darkness' in the Bible

They stopped asking, “Where is the Lordwho brought us from the land of Egypt,who led us through the wilderness,through a land of deserts and ravines,through a land of drought and darkness,a land no one traveled throughand where no one lived?”

Evil generation,pay attention to the word of the Lord!Have I been a wilderness to Israelor a land of dense darkness?Why do My people claim,“We will go where we want;we will no longer come to You”?

Give glory to the Lord your Godbefore He brings darkness,before your feet stumbleon the mountains at dusk.You wait for light,but He brings darkest gloomand makes thick darkness.
