5. In all these cases consider whether it would not be well to remember the words, "Thou shalt not remove the ancient landmarks which thy fathers have set." Nor do I say this because I shun the labour of investigating the Jewish Scriptures, and comparing them with ours, and noticing their various readings. This, if it be not arrogant to say it, I have already to a great extent done to the best of my ability, labouring hard to get at the meaning in all the editions and various readings; while I paid particular attention to the interpretation of the Seventy, lest I might to be found to accredit any forgery to the Churches which are under heaven, and give an occasion to those who seek such a starting-point for gratifying their desire to slander the common brethren, and to bring some accusation against those who shine forth in our community. And I make it my endeavour not to be ignorant of their various readings, lest in my controversies with the Jews I should quote to them what is not found in their copies, and that I may make some use of what is found there, even although it should not be in our Scriptures. For if we are so prepared for them in our discussions, they will not, as is their manner, scornfully laugh at Gentile believers for their ignorance of the true reading as they have them. So far as to the History of Susanna not being found in the Hebrew.
