4575. 'And kings will go out from your loins' means truths from the Divine Marriage. This is clear from the meaning of 'kings' as truths, dealt with in 1672, 1728, 2015, 2069, 3009, 3670, and from the meaning of 'the loins' as the things of conjugial love, dealt with in 3021, 4277, 4280, and therefore as the things of the heavenly marriage, and in the highest sense of the Divine Marriage. Truths from the Divine Marriage proceed from the Lord's Divine Human and are called holy; for the Lord's Divine Human is the Divine Marriage itself, and the things proceeding from that Marriage are holy. These are called celestial and spiritual, and they constitute the heavenly marriage, which is the marriage of truth joined to good, and of good joined to truth. This marriage exists in heaven and in every person who has heaven within him It also exists in every person within the Church, if good and at the same time truth are present in him.
