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.

3013. The process of introduction is described in the internal sense as follows: When the state was reached in which all things had been rearranged by the Lord into a Divine celestial order so that Divine Truth might be joined to the Divine Good of His Rational - a re-arrangement achieved through the normal channel from the natural man, that is to say, from the facts, cognitions, and matters of doctrine in the natural man - truths were at that point summoned from there by means of the Lord's Divine influx, introduced into good in the rational, and made Divine. Thus the Rational was made Divine by the Lord as regards truth as well as regards good.
