The answer is: Keturah

Gen 25:1

Abraham, iconic for his steadfast faith and parental legacy, had a fascinating later chapter in his life when he married a woman named Keturah after the death of Sarah, his first wife. Their union wasn’t merely a romantic one; it also amplified his family tree. The connection with Keturah resulted in several children, revealing both a narrative of renewal and the expansion of Abraham's lineage.

This new marriage is found in Genesis 25:1-6, where it mentions her children: Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. Interestingly, in the broader biblical context, the Midianites, descended from Abraham and Keturah’s son Midian, later become significant—entering the narrative when Moses flees Egypt and finds refuge among them. So, even if Keturah might seem like a side character, her lineage absolutely shimmies into the spotlight of Biblical history!

Speaking of names, Keturah's very name means "perfume" or "incense" in Hebrew, suggesting a sense of sweetness and fragrance associated with her presence in Abraham's life. It's intriguing how sometimes the lesser-known figures in the scriptures can hold major roles in the unfolding story of humanity's journey in witnessing faith, family, and multifaceted relationships. Just think—without Keturah, we might not have the rich tapestry of stories from the descendants who originated from their union!
