Claim: Keturah was Abraham's second wife.

Keturah was a concubine and wife of the Biblical patriarch Abraham . According to the Book of Genesis , Abraham married Keturah after the death of his first wife , Sarah ; Abraham and Keturah had six sons .   One modern commentator on the Hebrew Bible has called Keturah `` the most ignored significant person in the Torah '' . Some Jewish scholars have believed Keturah to be the same person as Abraham 's concubine Hagar , but this view is not universally held .
