1. Eliphaz' concubine, mother of Amalek (Genesis 36:12; Genesis 36:22); in 1 Chronicles 1:36 Timna is not, as apparently, a son of Eliphaz. Probably sister of Lotan, daughter of the Horite Seir. The feminine form of Timna shows that it is introduced in Chronicles as an abbreviation for what the chronicler knew his readers understood from Genesis, namely, that Timna was mother of "Amalek," which follows.
2. A duke or phylarch of Edom (Genesis 36:40-43), so that Timna was probably the name of a district.
