Contradiction with Genesis 36:11
This verse lists Eliphaz's sons as Teman, Omar, Zepho, Gatam, and Kenaz, but does not include Amalek, who is mentioned in 1 Chronicles 1:36.
Genesis 36:11: And the sons of Eliphaz were Teman, Omar, Zepho, and Gatam, and Kenaz. [Zepho: or, Zephi]
Contradiction with Genesis 36:12
Clarifies that Amalek was the son of Eliphaz by a concubine named Timna, which may cause confusion in the lineage mentioned in 1 Chronicles 1:36.
Genesis 36:12: And Timna was concubine to Eliphaz Esau's son; and she bare to Eliphaz Amalek: these [were] the sons of Adah Esau's wife.
