The answer is: Keturah

Gen 25:1

Abraham's second wife, Keturah, emerges from the scriptural story not merely as a figure in his life but as a bridge to a broader understanding of his legacy. Found in Genesis 25:1, Keturah's mention follows the more commonly explored partnership between Abraham and Sarah, providing a fascinating glimpse into the patriarch's life after Sarah's death.

The name “Keturah” itself means “incense,” suggesting a richness and aroma often associated with her character and the new beginnings she brought into Abraham’s life. After her marriage to Abraham, Keturah bore him several children, including Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. This addition to Abraham’s lineage underscores a theme in biblical narratives: God’s blessing is often received and multiplied in unexpected ways.

Interestingly, the Midianites, descendants of Keturah's son Midian, played significant roles in biblical history, including later encounters with Moses. The historical junctions that sprung from Keturah’s presence serve as reminders that while primary figures often dominate biblical accounts, secondary characters can also hold immeasurable importance.

Moreover, Keturah's story serves as an echo of concepts revolving around family and covenant. It further showcases the phasing of divine promise and how it weaves through the intricacies of human relationships, reminding readers that beyond one main story, many elements blend together to fulfill a greater narrative fabric. What an enlightening twist lives can have!
