In the book of Exodus, God instructs Moses in the design and construction of the tabernacle including a description of the garments to be worn by the priests. As part of this outfit, the priests were to construct and wear a breastplate (Exodus 28:15-30) which contained twelve different stones arranged and set in gold filigree. Each of the stones is specified in their order, and each stone is to have one of the names of the tribes of Israel engraved upon it. With the level of descriptive detail given to this priestly accessory, one might wonder what significance it holds for God followers.
Some have tried to attach symbolic significance to each of the stones and the tribe for which they represented. While this is a plausible suggestion, the scripture does not explicitly make this connection. This kind of interpretation is made especially difficult by our ability to identify the stones named in the description. Susan Meschel, a professor of materials science, reviewed the work of various researchers who surveyed both biblical and other ancient near east texts to try and discern the identity of each stone named in the breastplate (2018). Her basic conclusion was that while we can make some good guesses as to what these stones might have been, we have no confidence what they actually were. The biblical naming of semi-precious stones was based on things like color and their source rather than any characteristic property. So, even though your English translation of the Bible assigns a name to each stone, they simply are guesses, and we should not try to ascribe any meaning to them.
Scripture says the breastplate with the stones was to be worn in the tabernacle “to bring them to regular remembrance before the Lord.” (Exodus 28:29) While Christians who are considered to be a royal priesthood (compare Exodus 19:5-6 and 1 Peter 2:9) don’t wear a breastplate today, I think we can reflect on God’s design of the breastplate to remind ourselves about a number of things regarding the people of God.
To tell the Israelites that the breastplate should be composed of gold and these semi-precious stones meant a lot of work. You couldn’t just pick up these stones down at the local mall. They had to be mined out of the earth. Mining in the ancient near east was back breaking, labor intensive and dangerous work. Collecting the stones was followed by an intense effort of smoothing and polishing of the stones. In this we should remember the great effort and sacrifice to which God has gone to bring his people together.
It should not go unnoticed that each of the stones in the breastplate are both beautiful and different. God loves diversity, and does not expect everyone in the church to conform to one specification. Each person comes to the church with different gifts and abilities which enable the body of Christ to function as a collective whole. Not referring to stones, but to body parts, the apostle Paul says, “If all were a single member, where would the body be? As it is, there are many parts, yet one body.” (1 Corinthians 12:19-20)
Once the stones for the breastplate had been smoothed and polished, they were also engraved. Each stone had a name of the tribe of Israel written upon it. While we don’t have much in our modern culture that relates to this, we still carry in our language the sense of permanence and surety when something is “written in stone.” This should remind us of the binding and everlasting covenant God has established with his people through the blood of Christ.
The use of stones in the breastplate should also remind us that God likes to use stones. When the pharisees demanded that Jesus silence his disciples for praising him on his entry into Jerusalem, Jesus said that “if these were silent, the very stones would cry out.” (Luke 19:40) It is a bit humbling to think that God says the rocks are just as good at praising him as we are. God also views his people to be stones which are to be used in building His temple (Ephesians 2:20-22 and 1 Peter 2:5). The people of God have important roles to play in glorifying God and building His kingdom. Let’s get to it!
