The answer is: Keturah

Gen 25:1

Keturah, Abraham's second wife, steps onto the scene later in the narrative of Genesis, specifically in chapter 25. After Sarah passed away, Abraham took Keturah as his wife and fathered several children, including Midian (the same Midian from whom the Midianites descended—interesting, right?). This adds nuance to the understanding of Abraham’s legacy, showing that his lineage didn’t end with Isaac and Ishmael alone.

Now here's a fascinating point to ponder: Keturah's name is often thought to mean "incense" in the Hebrew language. It’s a beautiful call to the aroma of devotion, much like how faith symbolizes the fragrance in a spiritual sense. Furthermore, after Abraham's death, Keturah’s children were sent away eastwards, which might hint at how Israel's ancestral narratives are often about both unity and diversity.

These additional layers challenge the exclusivity sometimes ascribed to Abraham's covenant with Isaac, revealing that God's story unfolds through various lines and histories, becoming visually rich with diversity rather than confined to a singular path. This sacrament of family expands the broader story beyond expectations and also teaches about multidisciplinary relationships and areas of faith outside Esaak's narrative arc. Fun trivia: Many Middle Eastern cultures honor both Isaac and Ishmael, with diversity being a significant part of their identity—paving the way for conversations about communal ties and shared spiritual roots!
