Exodus 28:21-23

Amplified Bible, Classic Edition

²¹ And the stones shall be twelve, according to the names of the sons of Israel, like the engravings of a signet, each with its name for the twelve tribes.

²² You shall make for the breastplate chains of pure gold twisted like cords.

²³ You shall make on the breastplate two rings of gold and put [them] on the two edges of the breastplate.
