Sirach 18:30
Ben Sira, Ecclesiasticus28 Every intelligent person knows wisdom, and praises the one who finds her. 29 Those who are skilled in words become wise themselves, and pour forth apt proverbs. 30 Do not follow your base desires, but restrain your appetites. 31 If you allow your soul to take pleasure in base desire, it will make you the laughingstock of your enemies. 32 Do not revel in great luxury, or you may become impoverished by its expense.
Clement of Alexandria The Instructor 2.10
PaedagogusThus in the Philebus, Plato, who had been the disciple of the barbarian philosophy, mystically called those Atheists who destroy and pollute, as far as in them lies, the Deity dwelling in them — that is, the Logos— by association with their vices. Those, therefore, who are consecrated to God must never live mortally (θνητῶς). Nor, as Paul says, is it meet to make the members of Christ the members of an harlot; nor must the temple of God be made the temple of base affections. Remember the four and twenty thousand that were rejected for fornication. But the experiences of those who have committed fornication, as I have already said, are types which correct our lusts. Moreover, the Pædagogue warns us most distinctly: Go not after your lusts, and abstain from your appetites; for wine and women will remove the wise; and he that cleaves to harlots will become more daring. Corruption and the worm shall inherit him, and he shall be held up as public example to greater shame. And again — for he wearies not of doing good — He who averts his eyes from pleasure crowns his life.
Notes and References
"... The eighty-fifth of the Apostolical Canons gives a list of the books of the Hebrew Canon, and adds the first three books of the Maccabees and the Wisdom of Sirach; these last four are not, however, included in the Canon, though the Wisdom of Sirach is specially recommended for the instruction of the young. Again, in the Apostolical Constitutions, 6:14, 15, quotations from Sirach are given with the same formula as those from the books of the Hebrew Canon, but in the list given in 2:57 of the same work, there is no mention of any of the books of the Apocrypha ... The evidence of Clement of Alexandria is conflicting; in his Paedagogus he quotes very often from Sirach, and speaks of it as 'scripture', from which it would evidently appear that he regarded it as canonical Scripture; but, according to Eusebius, Clement reckoned Sirach among the 'Antilegomena', for in speaking of Clement's works he mentions the Stromateis, or 'Medleys', and says: 'He quotes in them passages from the disputed Scriptures, the so-called Wisdom of Solomon, for example, and of Jesus the son of Sirach, and the Epistle to the Hebrews, and those of Barnabas, Clement, and Jude ..."
