XXX. (140) Very properly, therefore, the most sacred Moses says that, the earth was corrupted at that time when the virtues of the just Noah were made manifest: "And the whole earth," says he, "was corrupted, because all flesh had corrupted his (autou) way upon the earth."40 (141) Now to some persons this expression will seem to have been incorrectly used, and that the consistency with the context, and the truth of the fact will require that we should read rather that, "All flesh had corrupted its (auteÂ̄s) way upon the earth." For it does not agree with the feminine noun "flesh" (teÌ„ sarki), if we subjoin a masculine case, the word autou in connection with it. (142) But perhaps, Moses does not mean here to speak of the flesh alone as corrupting his way upon the earth, so that he deserves to be considered to have erred in the expression which he has used, but rather to speak of the things of the flesh, which is corrupted, and of that other being whose way the flesh endeavours to injure and to corrupt. So that we should explain this expression thus:—All flesh corrupted the perfect way of the everlasting and incorruptible being which conducts to God. (143) And know that this way is wisdom. For the mind being guided by wisdom, while the road is straight and level and easy, proceeds along it to the end; and the end of this road is the knowledge and understanding of God. But every companion of the flesh hates and repudiates, and endeavours to corrupt this way; for there is no one thing so much at variance with another, as knowledge is at variance with the pleasure of the flesh. Accordingly, the earthly Edom is always fighting with those who wish to proceed by this road, (144) which is the royal road for those who partake of the faculty of seeing who are called Israel; for the interpretation of the name Edom, is "earthly," and he labours with all earnestness, and by every means in his power, and by threats, to hinder them from this road, and to make it pathless and impracticable for ever.
