Exodus 39:9
It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled.
Exodus 39:9 (KJV)
Context
In Exodus 28, God gave Moses detailed instructions for the priestly garments that Aaron and his sons would wear while serving in the tabernacle. Exodus 39 records the actual making of those garments, showing that the craftsmen followed God’s commands with care. This verse describes the completion of the high priest’s breastplate, a key piece of the priestly garments.
Meaning
This verse describes the breastplate as “foursquare” and “doubled.” Foursquare means it had four equal sides and four right angles, a perfect square. A span was about nine inches or twenty-five centimeters. The doubling means the fabric was folded in half to form a pouch or pocket. This matches the original command in Exodus 28:16, where God gave the same measurements and shape. The foursquare shape symbolizes perfection, completeness, and firmness.
The breastplate was made of gold, blue, purple, scarlet, and fine-twined linen. It held twelve precious stones, each engraved with the name of one of the twelve tribes of Israel, as described in Exodus 28:21. The doubling created a pocket that would hold the Urim and Thummim, sacred objects used by the high priest to seek God’s guidance for the nation. These lots were unique to the Old Testament priesthood.
Biblical connections
The foursquare shape appears again in Revelation 21:16, where the New Jerusalem is described as foursquare. In both places, the square shape suggests perfection, completeness, and stability. The breastplate worn over the high priest’s heart shows that he carried the people of Israel before God. This connection helps us see that God values order, wholeness, and faithful representation. The square also points to the perfection and stability of the church of Christ.
Application
The Urim and Thummim are not present today, and they were unique to the Old Testament priesthood. Yet the principle of seeking God’s wisdom remains. We can learn to bring our decisions before God in prayer, asking Him to guide us. We can also follow the example of the high priest by carrying the needs and concerns of others in our hearts as we intercede for them. This is a practical way to love our neighbors and serve God.
Reflection
The careful making of the breastplate reminds us that God notices how we serve Him. The craftsmen did not rush or improvise; they followed the pattern God gave. In our own lives, we can honor God by giving attention to the details of our worship and service. The square shape also points to a life that is balanced and complete, grounded in God’s truth and love. Let us seek His guidance and carry others in prayer, just as the high priest did.
