And this covenant is well said to be a shady and thick mountain, because it is darkened by the thick obscurities of allegories. Again, by a mountain is designated the apostate angel, as is said to preachers concerning the ancient enemy under the character of the king of Babylon, “Lift you up a banner upon the gloomy mountain.” Holy preachers lift up a banner above the gloomy mountain when they exalt the virtue of the cross. - "Morals on the Book of Job 6.33.2"
Hence it is often said to sinners: give glory to God! But Babylon and the entire region of the Chaldeans are called dark or gloomy mountains, as in the beginning of Isaiah, where we find written against Babylon: “Raise the signal on a dark mountain,” which in Hebrew is called nishpeh. - "Six Books on Jeremiah 3.17.2–3"
