Keturah is a wife of Abraham, whom he married probably after Sarah’s death (Genesis 25:1-6).
Abram had 6 sons by Keturah, whom he sent away into the east country. Her nationality is unknown.
She is styled “Abraham’s concubine” (1 Chronicles 1:32). Through the offshoots of the Keturah line Abraham became the “father of many nations.”
