The answer is: An onyx

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

In the captivating saga of the Exodus, the twelve tribes of Israel each had their names engraved on precious stones—specifically onyx stones. The significance of this practice isn’t just about bling for the priest! Each gemstone on the High Priest’s ephod served a symbolic purpose, representing a direct link between the people and the divine.

The onyx itself is fascinating; its layered appearance can remind us of the numerous dimensions of identity among the tribes. In ancient cultures, stones were not just ordinary items; they were loaded with meaning and connected to divine favor. Each tribe buzzing with its unique stories, struggles, and triumphs would resonate through the etched names.

Did you know that in biblical times, priestly garments weren’t just functional? They were fashion statements with a higher calling! The colors and materials used for priests’ garments denoted their elevated status and holiness in Israelite society. For example, the ephod itself was made from the finest fabrics: gold, purple, blue, and scarlet — consistent with meticulous attention to detail as a reflection of reverence to God.

Furthermore, this act of placing names on stones evokes the broader theme of remembrance throughout the Scriptures. Just as these stones would ensure the tribes were remembered before God, various biblical accounts encourage believers to build memorials, erect altars, and celebrate gatherings to remember their history, woven with God’s promises and providence. The sheer legacy of these engraved names adds a treasure trove of understanding when interpreting Israel's journey throughout the ages!
