'Gloom' in the Bible

Give glory to the Lord your God,Before He brings darknessAnd before your feet stumbleOn the dusky mountains,And while you are hoping for lightHe makes it into deep darkness,And turns it into gloom.

“Therefore their way will be like slippery paths to them,They will be driven away into the gloom and fall down in it;For I will bring calamity upon them,The year of their punishment,” declares the Lord.
