George Leo Haydock, on Jdt 8:1

Idox. Greek, “ox,” &c. All the versions disagree, as the copyists have probably taken in part of ver. 3 too soon, supposing that the genealogy of women was never given. St. Fulgentius (ep. ad Gallam) differs from all, giving the ancestors of Manasses as the same with those of Judith. (Calmet) — Simeon, the son of Ruben. In the Greek, it is, the son of Israel. For Simeon, the patriarch, from whom Judith descended, was not the son, but the brother of Ruben. It seems more probable, that the Simeon and the Ruben here mentioned are not the patriarchs, but two of the descendants of the patriarch Simeon: and that the genealogy of Judith, recorded in this place, is not carried up so high as the patriarchs. No more than that of Elcana, the father of Samuel, (1 Kings i. 1.) and that of king Saul, 1 Kings ix. 1. (Challoner) — Others think that Judith descended from Ruben, by her father, and from Simeon, by her mother; (Estius) or that, instead of son of Ruben, we should read “brother.” But as we know that Judith calls Simeon her father, (chap. ix. 2.) it is more likely that Ruben has been placed for Israel, as it is in Syriac, St. Fulgentius, &c. This correction is maintained by Bellarmine, Salien, Menochius. (Calmet) — Thus both Judith and her husband were of the same tribe, the former by Salathiel, the latter by Sarisadai. (Calmet) — Innumerable are the mistakes in the proper names, in Scripture. (Haydock) — Some of these might have had more than one. Greek has Sarasdai, (Complutensian, “Saladai;” Alexandrian Septuagint, “Salasadai.”) instead of Simeon, son of Israel: (Calmet) Alexandrian Septuagint, “ Jeel, ” which is probably a contraction for Israel.
