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.”6    Prov. xxii. 28.  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;7    Origen’s most important contribution to biblical literature was his elaborate attempt to rectify the text of the Septuagint by collating it with the Hebrew original and other Greek versions.  On this he spent twenty-eight years, during which he travelled through the East collecting materials.  The form in which he first issued the result of his labours was that of the Tetrapla, which presented in four columns the texts of the LXX., Aquila, Symmachus, and Theodotion.  He next issued the Hexapla, in which the Hebrew text was given, first in Hebrew and then in Greek letters.  Of some books he gave two additional Greek versions, whence the title Octapla; and there was even a seventh Greek version added for some books.  Unhappily this great work, which extended to nearly fifty volumes, was never transcribed, and so perished (Kitto, Cycl.). 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.

Πρὸς ταῦτα δὲ σκόπει, εἰ μὴ καλὸν μεμνῆσθαι τοῦ: »Οὐ μεταθήσεις ὅρια αἰώνια, ἃ ἔστησαν οἱ πρότεροί σου;« Καὶ ταῦτα δὲ φημὶ οὐχὶ ὄκνῳ τοῦ ἐρευνᾷν καὶ τὰς κατὰ Ἰουδαίους Γραφὰς, καὶ πάσας τὰς ἡμετέρας ταῖς ἐκείνων συγκρίνειν, καὶ ὁρᾷν τὰς ἐν αὐταῖς διαφοράς. Εἰ μὴ φορτικὸν γοῦν εἰπεῖν, ἐπὶ πολὺ τοῦτο, ὅση δύναμις, πεποιήκαμεν, γυμνάζοντες αὑτῶν τὸν νοῦν ἐν πάσαις ταῖς ἐκδόσεσι καὶ ταῖς διαφοραῖς αὐτῶν, μετὰ τοῦ ποσῶς μᾶλλον ἀσκεῖν τὴν ἑρμηνείαν τῶν Οʹ: ἵνα μή τι παραχαράττειν δοκοίημεν ταῖς ὑπὸ τὸν οὐρανὸν Ἐκκλησίαις, καὶ προφάσεις διδῶμεν τοῖς ζητοῦσιν ἀφορμὰς, ἐθέλουσι τοὺς ἐν μέσῳ συκοφαντεῖν, καὶ τῶν διαφαινομένων ἐν τῷ κοινῷ κατηγορεῖν. Ἀσκοῦμεν δὲ μὴ ἀγνοεῖν καὶ τὰς παρ' ἐκείνοις, ἵνα, πρὸς Ἰουδαίους διαλεγόμενοι, μὴ προφέρωμεν αὐτοῖς τὰ μὴ κείμενα ἐν τοῖς ἀντιγράφοις αὐτῶν, καὶ ἵνα συγχρησώμεθα τοῖς φερομένοις παρ' ἐκείνοις: εἰ καὶ ἐν τοῖς ἡμετέροις οὐ κεῖται βιβλίοις: τοιαύτης γὰρ οὔσης ἡμῶν τῆς πρὸς αὐτοὺς ἐν ταῖς ζητήσεσι παρασκευῆς, οὐ καταφρονήσουσιν, οὐδ' ὡς ἔθος αὐτοῖς, γελάσονται τοὺς ἀπὸ τῶν ἐθνῶν πιστεύοντας, ὡς τ' ἀληθῆ καὶ παρ' αὐτοῖς ἀναγεγραμμένα ἀγνοοῦντας. Ταῦτα μὲν οὖν εἰρήσθω πρὸς τὸ μὴ φέρεσθαι παρ' Ἑβραίοις τὰ περὶ Σωσάννης.
