New Defender's Study Bible Notes
15:1 the children of Judah. Caleb had been Judah’s representative among the twelve spies, and Hebron, his inheritance, was in the lot assigned to Judah. The latter was assigned first of all partly because of Caleb, but also because of Judah’s large size (Numbers 26:22) and probably also because of the leadership role originally prophesied for Judah by Jacob (Genesis 49:10).
15:32 twenty and nine. There are evidently listed in Joshua 15:21-32 a total of thirty-six “cities...with their villages.” Apparently Joshua included the names of seven “villages” as well as the twenty-nine “cities” (note also “Hazor” is mentioned three times).
