3915. And she shall bear upon my knees. That this signifies acknowledgment in the affection of interior truth, from which there is conjunction, is evident from the signification of "bearing," as being to acknowledge in faith and act (see n. 3905); and from the signification of "knees," or "thighs," as being the things that belong to conjugial love (n. 3021); thus the things that belong to the conjunction of the truth of faith with the good of love; for this conjunction is the very conjugial principle in the Lord's kingdom. Thus "bearing upon my knees" signifies an acknowledgment of the interior truth represented by Rachel. The custom among the ancients of sons and daughters being acknowledged as legitimate who were born of handmaids by consent of the wife, and brought forth upon her knees in order that they might be acknowledged, was derived from the Ancient Church, whose worship consisted in rituals that were representative and significative of celestial and spiritual things. In that church, because "bearing" signified the acknowledgment of truth, and "knees" conjugial love, thus the conjunction of good and truth from affection, such a ritual was accepted when the wife was barren, to the intent that she might not represent the dead who do not rise again to life (according to what has been said just above, n. 3908).
 In the internal sense by these words there is signified a second degree of affirmation or acknowledgment, which is from affection; for in order that the conjunction may take place, there must be affection within the acknowledgment or affirmation; for all conjunction is effected by means of affection, because without affection truths have no life. For example: to know the truths that the neighbor must be loved, and that charity consists in this, and in charity spiritual life, is bare memory-knowledge, unless attended with affection, that is, unless they are willed from the heart. Without affection these truths do not live, and however well anyone knows them, he nevertheless does not love his neighbor, but himself more than him, and he is in natural life, but not in spiritual life. It is natural affection that rules over spiritual affection, and so long as natural affection rules, the man is called "dead," for he has a life contrary to heavenly life, and heavenly life is the veriest life.
