Exodus 28:28 "That the Breast-plate be not loosed from the Ephod"

The Breast-plate, or "Cho-shen", is one of the most beautiful parts of the High Priest's clothes. It was woven with threads of gold, colored wool and braided linen.

It was inlaid with four rows of precious stones, such as emeralds and sapphires, that were placed within gold settings.

On each one of the stones, a name of one of the twelve tribes was engraved.

The Breast-plate was attached to the "Ephod", the apron that the High Priest wore. On its corners were rings. Sky-blue twisted threads of wool were laced through the rings and tied to the apron, holding the Breast-plate firmly in place.

We are prohibited from detaching the Breast-plate from the Ephod.
