Dark speech or a dark saying is a term used in Scripture. In Psalm 78:1-2, it says, “Give ear, O my people, to my law: incline your ears to the words of my mouth. I will open my mouth in a parable: I will utter dark sayings of old….”

In Hebrew, a dark saying, (Chîydâh) means, a puzzle, hence, a trick, conundrum, sententious maxim:—dark saying (sentence, speech), hard question, proverb, riddle.
