The answer is: Keturah

Gen 25:1

Abraham’s relationship with Keturah gives us a fascinating peek into the patriarch’s later life, highlighting that his journeys and encounters were not just limited to the land of Canaan. After Sarah’s passing, Abraham married Keturah, a detail found in Genesis 25:1. Was she introduced earlier? Unfortunately, her background before joining Abraham is shrouded in mystery. It’s believed that Keturah might have been a concubine, a detail that fits a common practice of the time.

An interesting twist is that Keturah bore Abraham six children! Their names — Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah — paint a vibrant tapestry of Abraham's legacy. Midian, in particular, should ring a bell for any Bible enthusiast! The descendants of Midian later become intertwined in the stories of Moses and Israel, creating broader connections and dynamics within Biblical narratives.

Keturah’s name itself is quite evocative, meaning “incense” or “fragrance,” perhaps signaling her most fruitful and aromatic contribution to Abraham’s story — not just a new family but also introducing non-Israelite elements into his lineage.

Keturah represents an important chapter in Abraham’s life, showing how, even in his older age, his life was marked by growth and new alliances. This continues the often-discussed theme of God's promises extending beyond initial, familiar boundaries, reflecting a broader narrative of connection in the unfolding drama of human experience.
