Ambrose of Milan : Nevertheless, I assert according to the Scriptures that He was able to spread out lowly places and open fields, just as He Himself says: 'I will walk before you and make mountains plain.' The force of the water itself could also make deeper things, which had settled, more turbulent: with such a movement of waves and such a surge of a more agitated element, which daily twists the depths of the sea and turns the sands out of the deep. — The Six Days of Creation, 3.15 John Chrysostom : Therefore, let us fear nothing so much as sin and transgression. Let us not fear punishment, and then we shall escape punishment. Even as the Three Children were not afraid of the furnace, and so escaped from the furnace. Such indeed it becomes the servants of God to be. For if those who were brought up under the Old dispensation, when death was not yet slain, nor his "brazen gates broken down," nor his "iron bars smitten in sunder;" so nobly encountered their end, how destitute of all defence or excuse shall we be, if, after having had the benefit of such great grace, we attain not even to the same measure of virtue as they did, now when death is only a name, devoid of reality. For death is nothing more than a sleep, a journey, a migration, a rest, a tranquil haven; an escape from trouble, and a freedom from the cares of this present life! — HOMILIES CONCERNING THE STATUES 7:1 Theodoret of Cyrus : By all that is about to be said, he has taught that he has invested Cyrus as king, he has given him the necessary sovereignty to direct his empire with good will and so that the disposition of difficult matters is mitigated and facilitated. This is what the phrase means: "I will level mountains, and I will break to pieces brazen doors." — COMMENTARY ON Isaiah 14:45.2
