1Chr 2:10

“Ram. He is commonly called Aram. But it is to be observed here, once for all, that it was a common thing among the Hebrews for the same person to have different names: and that it is not impossible among so many proper names, as here occur in the first nine chapters of this book, that the transcribers of the ancient Hebrew copies may have made some slips in the orthography. (Challoner) — Juda. Probably the first, appointed by Moses in the desert, Numbers i. 7., and vii. 12.”

“And Caleb the son of Hezron,.... The same that is called Chelubai, Ch1 2:9 but not the same with Caleb the son of Jephunneh, made mention of in the books of Numbers, Joshua, and Judges: he begat children of Azubah his wife, and of Jerioth; who were both his wives; or it may be rather, since Azubah is so particularly called his wife, Jerioth might be a concubine: or of Azubah he begat Jerioth; so the Vulgate Latin, Syriac, and Arabic versions; though it seems best with Hillerus (p) to interpret these names of the same person, and render the last clause, "that is, of Jerioth", of her whose name also was Jerioth, Azubah having two names; and the rather, since only the children of one are mentioned, as follows: her sons are these; Jesher, and Shobab, and Ardon of whom we read nowhere else; the Targum says, Azubah was so called, because she was barren and despised, which this clause contradicts. (p) Onomastic. Sacr. p. 568.”
