I looked up the verses in my DR then found v8 and v9 and v15 in my NAB After verse 20.
Why you may ask?
I quote from the *Preface to the New American Bible, The Old Testament:*In some instances in the Book of Job, in Proverbs, Sirach, Isaiah,
Jeremiah, Ezekiel, Hosea, Amos, Micah, Nahum, Habakkuk, and Zechariah there is good reason to believe that the original order of lines was accidentally disturbed in the transmission of the text. The verse numbers given in such cases are always those of the current Hebrew text, though the arrangement differs. In these instances the textual notes advise the reader of the difficulty. Cases of exceptional dislocation are called to the reader’s attention by footnotes.
As the OP noted, there is no footnote here. I guess this was not a case of “exceptional dislocation.” What about those “textual notes”? Back to the *Preface:*Where the translation supposes the received text—Hebrew, Aramaic, or Greek, as the case may be—ordinarily contained in the best-known editions, as the original or the oldest extant form, no additional remarks are necessary. But for those who are happily able to study the original text of the scriptures at firsthand, a supplementary series of textual notes pertaining to the Old Testament was added originally in an appendix to the typical edition. (It is now obtainable in a separate booklet from The Catholic Biblical Association of America, The Catholic University of America, Washington, DC 20064.) These notes furnish a guide in those cases in which the editorial board judges that the manuscripts in the original languages, or the evidence of the ancient versions, or some similar source, furnish the correct reading of a passage, or at least a reading more true to the original than that customarily printed in the available editions.
If you really want some exercise, try comparing Esther in the NAB to the Douay-Rheims. By the way, you may notice 1 & 2 Maccabees follows Esther in the NAB. Yeah, they moved whole books, too.
