The answer is: Mara

Ruth 1:20 - Naomi, reflecting her profound loss and sorrow after the death of her husband and sons, chose the name "Mara," which signifies bitterness. This poignant moment emphasizes her emotional state and sets the stage for her eventual restoration through Ruth's loyalty and God's providence in Bethlehem.

The story of Naomi and her name change to Mara is not just a simple tale of loss but a deep dive into human emotions and resilience. "Mara," meaning bitterness, is an apt representation of Naomi's heartbreak after significant losses. It's fascinating how names in biblical times carried more than just a label; they often reflected the essence and journey of a person's life.

In the book of Ruth, this narrative leads us to a rich tapestry of hope and redemption. Ruth's unwavering loyalty to Naomi serves as a stark contrast to the bitterness implied by the name. Their relationship not only uplifts Naomi from her sorrow but also represents a turning point historically for the lineage that would lead to King David and, ultimately, to the New Testament.

Interestingly, there is an Old Testament echo of the term "Mara" in the story of the waters at Marah—the place Moses led the Israelites to after their escape from Egypt, where they found bitter water. God instructed Moses to throw a piece of wood into the water, which transformed it from bitter to sweet. Similarly, Naomi’s bitter story shifts when Ruth clings to her, bringing hope and future reconnection to a community.

Such stories remind us that feelings of bitterness can be transformed. Often what begins in pain can lead to unexpected blessings, reinforcing a powerful message of faith and renewal in the face of despair.
