Gênesis 4:15
Indeed, it was not without reason that the mark was set upon Cain, that no one might kill him. Thus it was indicated that evil is not destroyed or removed from the earth. Cain was afraid that he might be killed, because he did not know how to flee. For evil is augmented and amassed by the practice of evil, and it exists without moderation or limit, fights through guile and deceit and is revealed by its deeds and by the blood of the slain, even as Cain also was revealed. — FLIGHT FROM THE WORLD 7.39
Gênesis 4:15
Therefore as a slave he received a sign, but even thus he could not escape death. Thus the sinner is a slave to fear, to cupidity, to avarice, to lust, to malice, to anger, nay, he is a greater slave than if he were set under tyrants. — Letter 37, To Simplician
