Arcana Coelestia#10491
10491. 'And the sons of Levi did according to the word of Moses' means put into effect by those in possession of truths springing from good. This is clear from the representation of 'the sons of Levi' as those in possession of truths springing from good, and in the abstract sense, without reference to persons, as truths springing from good, dealt with above in 10485; and from the meaning of 'doing according to the word of Moses' as putting into effect.
Arcana Coelestia#9888
9888. 'Before the face of it' means to eternity. This is clear from the meaning of 'before the face' as to eternity; for 'the breastplate' means heaven and every good and truth that constitutes it, 9879. What is 'before the face' in heaven is in the Lord's everlasting sight, thus is preserved to eternity.
