Jeremiah 49:16

Thy terrible-ness hath deceived thee, the fact that other nations seemed to stand in awe of Edom had caused him to think that he was really formidable, and the pride of thine heart, insolence usually having this influence upon the heart of the proud, to deceive them, wherefore the Lord now calls out, O thou that dwellest in the clefts of the rock, that boldest the height of the hill, some of the forts of Idumea being situated on almost inaccessible cliffs, though thou shouldest make thy nest as high as the eagle, I will bring thee down from thence, saith the Lord, showing that before Him no stronghold is impregnable.
