“By night I am overwhelmed by my problems, in the grip of discouragement like a kind of sleep. But if the light of your assistance shines, it will disperse the darkness of trouble and put an end to the sleep of discouragement. If, however, you delay your help, I am afraid the sleep will turn into death, as the distress becomes stronger than my resolve.”
(Theodoret of Cry ‘Commentary on Psalms’)
