And Aaron shall bear the names of the children of Israel in the breastplate of judgment on his heart, when he goes in to the holy place…
That the connection between the priest and the people might be made more plain, God not only placed on his breast the memorials of the twelve tribes, but also engraved their names on his shoulders. Thus the people would understand that this one man was not separated from the others for the sake of private advantage, but that in his one person they were all a kingdom of priests (see 1 Peter 2:5; Isaiah 66:21; Revelation 1:6). Hence arises our confidence of ascending to heaven because Christ raises us up with Him; we "sit together in heavenly places in Christ Jesus"; however weak we may be in ourselves, herein is all our strength that we are His burden.
( J. Calvin.)
