Translation - Latin-English - horum autem distributore gratiarum iuxta...

But since the Holy Ghost, who distributes graces according to His copious goodness, assignes the first division of these books, of course we have unrolled the book of the law going through the whole Pentateuch of Moses to the point of laying a hand on Joshua, as we were relieved from a due; then, after having discussed about the books of the law, it's logical to discuss about the books of the prophets.
