And the children of Lotan were Hori and Heman,.... The first of these seems to have his name from the general name of the tribe or nation, and the other is called Homam, 1-Chronicles 1:39,
and Lotan's sister was Timna: whom Eliphaz the firstborn of Esau took for his concubine, Genesis 36:12; for the sake of which her relation to Lotan is here mentioned; and she is said to be the sister of this man particularly, though there were seven brethren of them, because she might be his sister both by father and mother's side, when she was not of the other only by the father's side.
