“(Verse 14.) And above all high mountains, and above all elevated hills. Just as for the variety of virtues, mountains and hills are called good things: so among the impious for the diversity of vices, and especially pride, some are mountains, some are hills, over which the day of the Lord will come, of which it is written in Ezekiel: Thus says the Lord God to the mountains and hills: behold, I will bring a sword upon you, and your high places shall be destroyed, and your altars shall be broken down, and the rest (Ezech. VI, 3).”
