Abraham’s main wife in the biblical tradition is Sarah.

Main wife: Sarah

  • Sarah is the central wife of Abraham in the Hebrew Bible and is described as the mother of his son Isaac , the child of the covenant promise.
  • She was originally named Sarai , and her story is closely tied to Abraham’s migration, the promise of numerous descendants, and the miraculous birth of Isaac in her old age.

Other women in Abraham’s life

  • Hagar , Sarah’s servant, became Abraham’s concubine and bore him Ishmael , but she is not usually called his “wife” in the core biblical text.
  • After Sarah died, the book of Genesis says Abraham took another wife named Keturah , who bore him several more children.
* Some later Jewish traditions identify **Keturah as Hagar** under a new name, while others treat them as two separate women.
