(Douay-Rheims)
Sirach 24:24-25 I am the mother of fair love, and of fear, and of knowledge, and of holy hope. In me is all grace of the way and of the truth, in me is all hope of life and of virtue.
(Vulgate)
Ego mater pulchrae dilectionis et timoris
et agnitionis et sanctae spei.
In me gratia omnis viae et veritatis,
in me omnis spes vitae et virtutis.
This is a beautiful verse from the old testament that for some reason is left out of modern catholic bibles like the RSV and NAB. Why is that? Is the Douay-Rheims better?
This is a case of different versions of the same work circulating around really. The Vulgate version of Sirach is a longer one compared to the Greek version used in the RSV and the NAB. Sirach has probably the most complicated textual history out of all biblical books (so complicated that scholars are still struggling to untie all the knots), but I’ll try to explain.
Both the Hebrew and the Greek textual traditions of Sirach have the text in a longer and a shorter form. The shorter Hebrew version (I’ll call it Hebrew I or
HI) is usually held to be the original work authored by Joshua ben Sira (aka Jesus son of Sirach’s) around the beginning of the 2nd century BC. Not long after 132 BC, Joshua’s grandson made a translation/slight adaptation into Greek of his grandfather’s work while he was in Egypt: the shorter Greek version found in the main
uncial manuscripts of the Septuagint, Greek I aka
GI, is usually held to be the (or at least a close representative of the) grandson’s Greek version. There’s also one or more secondary Hebrew texts - probably of later date than the author’s grandson’s Greek translation - which contained various expanded readings (Hebrew II or
HII), and then an expanded Greek text based more or less on HII (Greek II or
GII) which also reflected the Stoic school of
Aristobulus of Paneas (ca. 160 BC) in Alexandria. This longer version, GII, was most likely the base for the
Old Latin version found in the Vulgate. (To be honest though, the exact relationship between the
Vetus Latina Sirach and the longer Greek version is still a matter of debate.)
For a similar case, I’d suggest you look at Tobit in the DR and compare it with the versions of Tobit in the RSV and the NAB. You’d notice that all three translations have a quite different text of the same book from each other. (The DR in particular differ from both the NAB and the RSV.)
That one we could ascribe to the DR, the RSV, and the NAB each using a different version of Tobit to translate from. (Just goes to show the necessity of using multiple translations.
