9601. 'And the breadth four cubits' means the marriage of truth to good. This is clear from the meaning of 'the breadth' as truth, dealt with in 1613, 3433, 3434, 4482, 9487; and from the meaning of 'four' as a joining together, dealt with in 1686, 8877, and so a marriage since truth and good joined together is called the heavenly marriage, 2173, 2618, 2728, 2729, 2803. 'Four' means a joining together or a marriage because this number is the product of two multiplied by itself, and 'two' means a joining together, 5194, 8423, multiple numbers being similar in meaning to the simple ones that are their factors, as stated immediately above in 9600. All numbers in the Word mean spiritual realities, see the places referred to in 9488.

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.
