Gregory of Nazianzus : Every time is suitable for your ablution, since any time may be your death. With Paul I shout to you with that loud voice, "Behold now is the accepted time; behold now is the day of salvation";56 and that now does not point to any one time but is every present moment. And again "Awake, you that sleep, and Christ shall give you light," dispelling the darkness of sin. For as Isaiah says, "In the night hope is evil," and it is more profitable to be received in the morning. — ON HOLY BAPTISM, ORATION 40:13 Gregory the Dialogist : Now righteous people conceive a dread of God before his indignation is stirred up against them; they fear him at rest, lest they should feel him as moved. But, on the other hand, the wicked then for the first time fear to be smitten when they are under the rod, and terror then rouses them from the sleep of their insensibility when vengeance is troubling them. And hence it is said by the prophet, "And only the vexing alone shall supply understanding to the hearing." For when they have begun to be stricken in vengeance for the contempt and neglect of God's precepts, then they understand the thing that they heard. — Morals on the Book of Job, Book 11, Section 41 Jerome : (Verse 19). When it passes by, it will seize you; for it will pass through in the morning, in the day and at night, and its vexation will only give understanding to the ear. LXX: When it passes, it will lift you up in the morning, it will pass in the morning; day and night there will be the worst of hope. Learn to listen, you who are in tribulation: we cannot fight, for we ourselves are weak to be gathered. For always the wrath of the Lord will fall upon you, and you will feel it both in times of prosperity and adversity, and cruel death will ravage you. What shall I say about punishments? Fear of punishments alone and the dread of torments will correct you for salvation, and will make you understand your evils. And when you have been tormented, then you will know that my Prophets have spoken the truth. According to the Hebrew. Furthermore, as for what is read in the LXX: Learn to hear, you who are troubled: we cannot fight, but we ourselves are weak so that we may gather together. I completely do not know the meaning of this, and how it is connected to the previous context. Unless perhaps the divine speech speaks to the leaders of the people and encourages them to have hope in God, and not in death and hell, and teaches them to listen to the prophecies of the prophets, and they respond that they cannot fight against opposing powers due to the weakness of their strength, nor gather among the people of God. — Commentary on Isaiah
