(133) A further difficulty attends this method in the case of some of the books of Scripture, namely, that they are no longer extant in their original language. (133) The Gospel according to Matthew, and certainly the Epistle to the Hebrews, were written, it is thought, in Hebrew, though they no longer exist in that form. (134) Aben Ezra affirms in his commentaries that the book of Job was translated into Hebrew out of another language, and that its obscurity arises from this fact. (135) I say nothing of the apocryphal books, for their authority stands on very inferior ground. (136) The foregoing difficulties in this method of interpreting Scripture from its own history, I conceive to be so great that I do not hesitate to say that the true meaning of Scripture is in many places inexplicable, or at best mere subject for guesswork; but I must again point out, on the other hand, that such difficulties only arise when we endeavour to follow the meaning of a prophet in matters which cannot be perceived, but only imagined, not in things, whereof the understanding can give a clear idea, and which are conceivable through themselves: [Endnote 8] matters which by their nature are easily perceived cannot be expressed so obscurely as to be unintelligible; as the proverb says, "a word is enough to the wise." (137) Euclid, who only wrote of matters very simple and easily understood, can easily be comprehended by anyone in any language; we can follow his intention perfectly, and be certain of his true meaning, without having a thorough knowledge of the language in which he wrote; in fact, a quite rudimentary acquaintance is sufficient. (138) We need make no researches concerning the life, the pursuits, or the habits of the author; nor need we inquire in what language, nor when he wrote, nor the vicissitudes of his book, nor its various readings, nor how, nor by whose advice it has been received. (139) What we here say of Euclid might equally be said of any book which treats of things by their nature perceptible: thus we conclude that we can easily follow the intention of Scripture in moral questions, from the history we possess of it, and we can be sure of its true meaning. (140) The precepts of true piety are expressed in very ordinary language, and are equally simple and easily understood. (141) Further, as true salvation and blessedness consist in a true assent of the soul - and we truly assent only to what we clearly understand - it is most plain that we can follow with certainty the intention of Scripture in matters relating to salvation and necessary to blessedness; therefore, we need not be much troubled about what remains: such matters, inasmuch as we generally cannot grasp them with our reason and understanding, are more curious than profitable.
