Arcana Coelestia #9909
9909. 'Over his heart before Jehovah continually' means for evermore shining forth from good. This is clear from the meaning of 'heart' as the good of love, dealt with in 3313, 3635, 3883-3896, 7542, 9050; and from the meaning of 'continually' as for evermore. Shining forth is meant because the breastplate was over the heart, and 'the breastplate' means Divine Truth shining forth from the Lord's Divine good, 9823.
Ezekiel 27:13

Javan, Tubal, and Meshech, they were your traffickers; they traded the persons of men and vessels of brass for your merchandise.
