But he calls these the mountains of eternity and the hills ages, which had been from the beginning fixed on their own foundations. For if an earthquake happens on a plain, it seems less wonderful; and then if any of those mountains cleave, which are not so firmly fixed, it may be on account of some hollow places; for when the winds fill the caverns, they are forced to burst, and they cleave the mountains and the earth. But the Prophet relates an unusual thing, and wholly different from the ordinary course of nature—that the mountains of eternity, which had been from the beginning, and had remained without any change, were thus demolished and bowed down. In short, the Prophet intended by all means to raise up to confidence the minds of the godly, so that they should become fully persuaded that God’s power to deliver them would be the same as that which their fathers had formerly experienced; for there is no other support under adverse, and especially under despairing circumstances, than that the faithful should know that they are still under the protection of that God who has adopted them. This is the reason why the Prophet amplifies, in so striking a manner, on the subject of God’s power.
