While specific commentary on this verse is limited, Matthew Henry uses the imagery of the priestly garments to point to Jesus. Just as the high priest's breastplate, bearing the names of Israel's tribes, was securely fastened near his heart, Christ our High Priest holds His people close. The instruction that the breastplate 'might not be loosed' can be seen as a beautiful picture of the security believers have, held permanently and lovingly by their Savior as He represents them before the Father.
