Exodus 28:24

And thou shalt put the two wreathen chains of gold in the two rings which are on the ends of the breastplate.

The two twisted chains of gold were to be placed in the two rings on the ends of the breastplate. This was one detail in God's specific directions to Moses for everything connected with tabernacle service, specifying the dress of those who minister before Him and requiring that their apparel be arranged according to His instructions. The priestly garments were to follow the particular style God specified, suited to the priests' work in the holy place.

The breastpiece and ephod were made for the high priest's service, and their sacredness came from being used in the worship God had directed. Only the high priest was authorized to wear them when appearing before the Lord, so Gideon's imitation of them gave him no authority to establish a separate worship. Aaron's garments were symbolic, showing that the dress of those who serve God is to represent Christ.

The high priest's breastplate was set with precious stones and served as a means by which messages from Jehovah were received. The flashing of God's glory upon those stones and the shadowing of His disapproval over them were signs of His presence over the earthly mercy seat. When Christ died the veil of the temple was torn from top to bottom and the most holy place was exposed, and from that time God's presence no longer overshadowed the mercy seat with light or shadow on the stones of the breastplate.

The precious, jeweled appearance of the breastplate and the names engraved on it are reflected in heaven, where Jesus wears a breastplate that glitters and magnifies letters resembling names. The apparel of those who officiate before God can honor or dishonor Him, and God requires order in everything and especially cleanliness. Care and order in sacred service taught the people reverence for God and the holiness of His work.
