And Caleb the son of Hezron
The same that is called Chelubai, ( 1 Chronicles 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 F16 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.
