The answer is: An onyx

Exo 28:9 - to be part of the priestly ephod

When it comes to the high priest’s attire in Exodus, the mention of onyx stones is fascinating! These beautiful, precious stones were not just for show; they were imbued with deep symbolism. On the breastplate of the high priest, the onyx stones served as a reminder of the unity of the tribes of Israel. Each stone represented one of the twelve children of Israel, echoing the desire for cohesion within the community and stability in their journey through the desert.

Now, if you dig a bit deeper, you might find it interesting that the Onyx stone isn't exclusive to the ancient Israelites. Ancient cultures from the Sumerians to the Romans have valued these layered stones. In fact, in ancient Rome, onyx was often associated with strength and protection – a powerful symbol especially for those facing the trials the Israelites encountered.

Adding another layer, the concept of engraved names recalls our need for connection and identity, something that has persisted throughout history. Just as the high priest carried the names of the tribes over his heart, people today often wear rings or bracelets that bear significant names or symbols. It’s a connection from generations past to the way we express our love and loyalty now.

So, next time you hear about those onyx stones from right in the book of Exodus, think not only of their physical beauty but the rich tapestry of relationships they illustrate for the wandering tribes, and for all of us seeking to unite and remember our roots.
