(15) Dukes.--Duke is the Latin word dux, a leader; but the Hebrew word alluph signifies a tribal prince, It is derived from eleph, a thousand, used in much the same way as the word hundred with us for a division of the country. Probably it was one large enough to have in it a thousand grown men, whereas a hundred in Saxon times was a district in which there were a hundred homesteads. For this use of it, see Micah 5:2. Each alluph, therefore, would be the prince of one of these districts, assigned to him as the possession of himself and his seed.

Verses 15, 16. - These were dukes of the sons of Esau. The אַלּוּפים, derived probably from אָלַפ, to be familiar, whence to join together, or associate, were Edomite and Horite phylarchs or tribe-leaders, ἡγεμόνες, (LXX.), chieftains of a thousand men (Gerlach). At a later period the term came to be applied to the Jewish chiefs or governors of the Restoration (Zechariah 9:7; Zechariah 12:5). The sons of Eliphaz the firstborn son of Esau; duke Teman, duke Omar, duke Zepho, duke Kemaz (vide on ver. 11), duke Korah, - inserted here probably by clerical error from ver. 18 (Kennicott, Tuch, Knobel, Delitzsch, Keil, Murphy, Quarry), and accordingly omitted in the Samaritan Pentateuch and Version, though still retained by Onkelos and the LXX., and on the hypothesis of its genuineness explained by some as the name of a nephew of Eliphaz (Junius); of a son by another mother (Ainsworth); of a son of Korah (ver. 18) by the widow of Timua (1 Chronicles 1:36), who, having died without issue, left his wife to his brother (Michaelis); of some descendant of Eliphaz by intermarriage who subsequently rose to be the head of a clan (Kalisch), - duke Gatam (vide ver. 11), and duke Amalek (vide ver. 12): these are the dukes that came of Eliphaz in the land of Edom; these were the sons of Adah.

36:1-43 Esau and his descendants. - The registers in this chapter show the faithfulness of God to his promise to Abraham. Esau is here called Edom, that name which kept up the remembrance of his selling his birth-right for a mess of pottage. Esau continued the same profane despiser of heavenly things. In outward prosperity and honour, the children of the covenant are often behind, and those that are out of the covenant get the start. We may suppose it a trial to the faith of God's Israel, to hear of the pomp and power of the kings of Edom, while they were bond-slaves in Egypt; but those that look for great things from God, must be content to wait for them; God's time is the best time. Mount Seir is called the land of their possession. Canaan was at this time only the land of promise. Seir was in the possession of the Edomites. The children of this world have their all in hand, and nothing in hope, Lu 16:25; while the children of God have their all in hope, and next to nothing in hand. But, all things considered, it is beyond compare better to have Canaan in promise, than mount Seir in possession.These were dukes of the sons of Esau,.... Ben Melech says, the difference between a duke and a king was, that a king is crowned and a duke is not crowned; but Jarchi interprets the word of heads of families, which seems probable; so that as Esau's sons and grandsons are before related, here it is suggested that they had large and numerous families, of which they were the heads and governors; and in this and the following verses, Genesis 36:16; the sons and grandsons of Esau by his several wives are rehearsed as in the preceding verses, with the title of "duke" given to each of them.
