And Timna was concubine to Eliphaz Esau’s son; and she bare to Eliphaz Amalek: these were the sons of Adah Esau’s wife.
Observe here, 1. That only the names of Esau's sons and grandsons are recorded, only their names, not their history; for it is the church that Moses preserves the records of, not the record of those that are without. Those elders that lived by faith alone obtained a good report. It is Sion that produces men of renown, not Seir, Psa 87:5.
Commenting on Genesis 36:9-19
And these are the sons of Reuel,.... Another son of Esau's; this man had four sons, as follow: Nahath, and Zerah, Shammah and Mizzah: of whom we know no more than their names, unless Maps or Massa, which Ptolemy (z) places in Idumea, should have its name from Mizzah: these were the sons of Bashemath, Esau's wife; her grandsons, as before. (z) Geograph. l. 5. c. 16.
Timna was concubine to Eliphaz - As Timna was sister to Lotan the Horite, Gen 36:22, we see how the family of Esau and the Horites got intermixed. This might give the sons of Esau a pretext to seize the land, and expel the ancient inhabitants, as we find they did, Deu 2:12.
