In Deuteronomy 15:11, this signifies that truth requires good and good truth, and always will. (Arcana Coelestia 5365)

In Psalm 21:5, this signifies that the Lord will to eternity deliver those deprived of truths and good against their will. (The Inner Meaning of the Prophets and Psalms 271, Apocalypse Explained 95)

2729. The derivation of genuine conjugial love from good married to truth may also be evident from the fact that it cannot exist with anyone unless good united to truth and truth to good from the Lord are present in him. That derivation may also be evident from the fact that heavenly blessedness and happiness reside in that love, and that everyone in whom that love exists comes into heaven, that is, into the heavenly marriage. It is also evident from the fact that when angels are talking about the union of good and truth, that which is a representative of marriage presents itself in a lower sphere among good spirits, but that which is a representative of adultery presents itself among evil spirits. This explains why in the Word the union of good and truth is called a marriage, but the adulteration of good and the falsification of truth is called adultery and whoredom, see 2466.
