Philo Judaeus De Praemiis Et Poenis Et De Exsecrationibus 72

[72] for the scripture says ¹ that God laid a curse upon the fratricide, so that he should be continually groaning and trembling. Moreover he put a mark upon him, that he might never be ² pitied by any one, so that he might not die once, but might, as I have said before, pass all his time in dying, amid griefs, and pains, and incessant calamities; and what is most grievous of all, might have a feeling of his own miseries, and be afflicted both with the evils which were before him, and also from a foresight of the number of misfortunes which were constantly impending over him, which nevertheless he was unable to guard against, since hope was wholly taken from him, which God has implanted in the race of mankind, in order that thus, having an innate comfort in themselves, they might feel their sorrows relieved, provided they had not committed any inexpiable crimes.
