'Gloom' in the Bible

"You, generation, pay attention to this message from the LORD! Am I the desert to Israel, or a land of gloom? Why do my people say, "We're free to roam? We won't come to you anymore.'

Give glory to the LORD your God before he brings darkness, before your feet stumble on the mountains at twilight. You hope for light, but he turns it into deep darkness. He changes it into heavy gloom.
