And Hezron which is Hazor - In this verse are the names of two towns only, not of four. Two places bearing the common topographical appellation, Hazor ("enclosure") are here mentioned and distinguished as "Hazor Hadattah" and "Kerioth-Hezron," otherwise termed Hazor, simply: the former has been identified by some with "El-Hudhera"; the latter is probably the modern "El-Kuryetein". Kerioth, prefixed to a name, bespeaks military occupation, as Hazor points to pastoral pursuits. The place would therefore seem to be an ancient pastoral settlement which had been fortified by the Anakims, and called accordingly Kerioth; to which name the men of Judah, after they had captured it, added that of Hezron, in honor of one of their leading ancestors (compare Genesis 46:12; Ruth 4:18). Kerioth was the home of Judas the traitor, if the ordinary derivation of Iscariot (= קריות אישׁ 'ı̂ysh qerı̂yôth), i. e. man of Kerioth) be accepted: Matthew 10:4.

And Hazor, Hadattah, and Kerioth, and Hezron, which is Hazor. According to the Targum, two cities only are here meant, which reads, "and Hazorhadattah, and Keriothhezron, which is Hazor"; and this reading seems to be right; there were three Hazors in this tribe, one in Joshua 15:23, and two more here, which are distinguished; the first is called Hazorhadattah, or new Hazor; of which Jerom says (e), there is a village at this day called Asor, in the borders of Ashkelon, to the east of it, which fell to the lot of the tribe of Judah; the Scripture makes mention of it, calling: it new Asor, to distinguish it from the old; and Keriothhezron is the same with Hezron, Joshua 15:3; and had also the name of Hezron. From this place Judas Iscariot is thought to have his name, being Ishceriot, a man of Keriot.
