Isaiah 2:19

The Creator ought to be known even by the light of nature, for he may be understood from his works and may thereby become the object of a more widely spread knowledge. To him, therefore, does it appertain to punish such as do not know God, for none ought to be ignorant of him. In the apostle's phrase, "From the presence of the Lord, and from the glory of his power," he uses the words of Isaiah, who for that same reason attests the very same Lord as arising "to shake terribly the earth."

(Verse 19) On that day, a man will cast away his silver idols and his gold images that he made for himself to worship moles and bats. He will enter the clefts of the rocks and the crevices of the cliffs, from the terror of the Lord and the splendor of His majesty, when He arises to shake the earth. We have often spoken of silver and gold in a figurative sense, expressing their capacity to speak or feel God, and praise their Creator, since they were given by God to humans for this purpose. However, they misuse this gift by using it to simulate idols, as it is written: I gave them silver and gold, but they used it to make Baal idols (Hosea 2:8). Therefore, when someone, terrified by the fear of the Lord, first places idols in the cave of their heart and hides them in the depths of the earth, not daring to bring forth what they have wrongly conceived, they make progress by throwing away what has been carved and refusing to allow it to exist within themselves. Concerning the moles, which we have interpreted as seventy, the Aquila put stones, Symmachus put unfruitful things, and Theodotion put the Hebrew word Pharpharoth(). Now, the animal is blind, always digging into the earth, excavating the soil, and feeding on roots, harmful to crops: the Greeks call it aspalax. The bat, however, is a nocturnal bird, which received its fitting name νυκτερὶς because it flies at night. It is a small animal, similar to a mouse, not resonating so much with voice and song, as with a shrill sound. Since it appears to be flying, it shuns the light and does not tolerate seeing the sun. Idols have been compared to creatures of this kind, which dwell in blind and dark worship: and all doctrines contrary to truth. When they have been abandoned on the day of the Lord, those who have rejected them will enter into the cracks of rocks and caverns of stones, so that they may not engage in the dust of the earth and cheap mud, but be involved in sound reasoning, and find various openings of virtues through which they may be able to reach the truth. I have briefly described in this anagoge, as best I could, the times and destruction of Jerusalem that the Hebrews refer to in Babylon, when the Lord rose to strike the land of the Jews.
