Job 13:26 - Joseph Benson’s Commentary on the Old and New Testaments

For thou writest That is, thou appointest; bitter things against me A terrible sentence, or most grievous punishments. It is a metaphor taken from the custom of princes or judges, who anciently used to write their sentences, or decrees, concerning persons or causes brought before them. And makest me to possess the iniquities of my youth Dost now, at once, bring upon me the punishment of all my sins, not excepting those of my youth, which were committed before I well knew what I did.
