'Morning After Morning' in the Bible

He said to him, “O son of the king, why are you so depressed morning after morning? Will you not tell me?” Then Amnon said to him, “I am in love with Tamar, the sister of my brother Absalom.”

“As often as it passes through, it will seize you;For morning after morning it will pass through, anytime during the day or night,And it will be sheer terror to understand what it means.”
