15 These were dukes of the sons of Esau: the sons of Eliphaz the firstborn son of Esau; duke Teman, duke Omar, duke Zepho, duke Kenaz, 

16 Duke Korah, duke Gatam, and duke Amalek: these are the dukes that came of Eliphaz in the land of Edom; these were the sons of Adah. 

17 And these are the sons of Reuel Esau’s son; duke Nahath, duke Zerah, duke Shammah, duke Mizzah: these are the dukes that came of Reuel in the land of Edom; these are the sons of Bashemath Esau’s wife. 

18 And these are the sons of Aholibamah Esau’s wife; duke Jeush, duke Jaalam, duke Korah: these were the dukes that came of Aholibamah the daughter of Anah, Esau’s wife. 

19 These are the sons of Esau, who is Edom, and these are their dukes.

We now continue with the descendants of Esau, and in these verses it specifically lists out the dukes, or tribal chiefs, among his sons and grandsons. Two of Esau’s wives had one son each. Through the first of these Esau obtained seven grandsons, each of which were given the title of duke. Through the second son came four more grandsons, also called dukes.

The pattern was slightly different with Esau’s third wife. Rather than bearing him a single son, Aholibamah gave birth to three, and all of these were also named dukes. Thus in all Esau had eleven duke grandsons and three duke sons, fourteen rulers to steer the clans of the Edomites.

Most of these dukes names I do not recognize, but the third one in verse sixteen is quite significant. Duke Amalek, I imagine, is the progenitor of the Amalekites, who would be a great rival to the Israelites when they returned from Egyptian captivity. This continues a pattern we have seen previously, where the kin of the covenant end up siring the very nations that would compete most hotly with the Israelites.
