From the same author, on #Ge 17:14.

The law does not treat any action done involuntarily as guilty, since it even pardons a man who has committed murder unintentionally; but if a child is not circumcised eight days after its birth, what evil has it done so as to be subjected to the punishment of death? Therefore some persons say that the manner of the punishment is to be referred to its parents, and think that they ought to be punished severely as having neglected the commandments of the law; and others think that it is by an excess of indignation that God is here represented as inflicting punishment, as far as appearance goes, on the child, in order that this inevitable punishment may be inflicted on those people of mature age who have violated the law.
