Arcana Coelestia #9902
9902. 'Over his heart' means out of Divine Love to eternity. This is clear from the meaning of 'heart' as the good of love, dealt with in 3313, 3635, 3883-3896, 7542, 9050, so that when the Lord, represented here by Aaron, is the subject, Divine Love is meant. This is why 'carrying over the heart' means preserving out of Divine Love to eternity.
