From the time that it goes forth it shall take you: for morning by morning shall it pass over, by day and by night: and it shall be a terror just to understand the report.
Read Chapter 28
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 3.11.41"
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”; 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"
