Sirach 23:6
Ben Sira, Ecclesiasticus4 O Lord, Father and God of my life, do not give me haughty eyes 5 and remove evil desire from me. 6 Let neither gluttony nor lust overcome me, and do not give me over to shameless passion. 7 Listen, my children, to instruction concerning the mouth; the one who observes it will never be caught. 8 Sinners are overtaken through their lips; by them the reviler and the arrogant are tripped up.
Augustine Confessions 10.31
Lo! A soldier of the celestial camp — not dust as we are. But remember, O Lord, that we are dust, and that of dust You have created man; and he was lost, and is found. Nor could he do this of his own power, seeing that he whom I so loved, saying these things through the afflatus of Your inspiration, was of that same dust. I can, says he, do all things through Him which strengthens me. Strengthen me, that I may be able. Give what You command, and command what You will. He confesses to have received, and when he glories, he glories in the Lord. Another have I heard entreating that he might receive —Take from me, says he, the greediness of the belly; by which it appears, O my holy God, that You give when what You command to be done is done.
Notes and References
"... As to Augustine’s use of the Book of Ecclesiasticus, it is striking that more than once he quotes a text that is somewhat different from the Vetus Latina, which for the Book of Ben Sira, serves as the traditional Latin text. Since Augustine’s quotations from the Book of Ben Sira have more than once been brought in line with the Greek translation, a thorough investigation into this phenomenon is needed in order to find out whether he had (some) knowledge of the Greek text of the Book of Ecclesiasticus. Apart from Speculum in which Augustine for his quotations from the Book of Ben Sira usually follows the Latin, in his other works he rather frequently appears to correct the Latin Ben Sira quotations according to the Greek. An investigation into this intriguing question would be very useful. Such an in depth inquiry should also take into full consideration whether, and to what extent, St. Augustine has been influenced by a text type of Ecclesiasticus that was already used by St. Cyprian and has even been given its own siglum (K) by Thiele ..."
