Spiritual Meaning of GENESIS 13:18
AC 1615. Verse 18. And Abram pitched his tent, and came and dwelt in the oak-groves of Mamre that are in Hebron, and there he built an altar to Jehovah. "Abram pitched his tent, and came and dwelt in the oak-groves of Mamre that are in Hebron, "signifies that the Lord came to a perception still more internal; this is the sixth state; "and there he built an altar to Jehovah," signifies worship from that state.
AC 1616. And Abram pitched his tent, and came and dwelt in the oak-groves of Mamre that are in Hebron. That this signifies that the Lord attained to a perception still more internal, is evident from the signification of "pitching a tent," that is, of moving and fixing a tent, as being to be conjoined,--for a "tent" is the holy of worship (n. 414, 1452), by which the external man is conjoined with the internal;--and from the signification of an "oak-grove," as being perception, as explained above (n. 1442, 1443), where it was "the oak-grove of Moreh," which is the first perception; but here, "the oak-groves of Mamre," in the plural, which signify more perception, that is, perception more internal. This perception is called "the oak-groves of Mamre that are in Hebron." "Mamre" is also mentioned elsewhere (Gen. 14:13; 18:1; 23:17-19; 35:27), and Hebron likewise (Gen. 35:27; 37:14; Josh. 10:36, 39; 14:13, 14, 15; 15:13, 54; 20:7; 21:11, 13; Judges 1:10, 20); but with what signification, will of the Lord‘s Divine mercy be seen where these passages are explained.
 As to "the oak-groves of Mamre that are in Hebron" signifying a still more internal perception, the case is as follows. As the things that are of the external man are conjoined with the celestial things of the internal man, so perception increases and becomes more internal. Conjunction with celestial things gives perception; for in the celestial things that are of love to Jehovah is the very life of the internal man; or what is the same, in the celestial things that are of love, that is, in celestial love, Jehovah is present, which presence is not perceived in the external man until conjunction has been effected, all perception being from conjunction.
 From the internal sense it is here evident how the case was with the Lord, namely, that His external man, or the Human Essence, was conjoined with the Divine Essence by degrees, according to the multiplication and fructification of knowledges. In no way can any one, as a man, be conjoined with Jehovah or the Lord, except by means of knowledges, for by means of knowledges a man becomes a man; and so the Lord, because born as are other men, was also instructed as they are, but into His knowledges as receptacles celestial things were constantly being insinuated, so that the knowledges continually became the recipient vessels of celestial things, and themselves also became celestial.
 He continually advanced in this way to the celestial things of infancy for, as before said, the celestial things that are of love are insinuated from the earliest infancy up to childhood, and also to youth, when being a man he is then and afterwards imbued with knowledges (scientiae et cognitiones). If the man is such that he can be regenerated, these knowledges are then filled with the celestial things that are of love and charity, and are thus implanted in the celestial things with which he has been gifted from infancy up to childhood and youth; and thus his external man is conjoined with his internal man. They are first implanted in the celestial things with which he was gifted in youth, next in those with which he was gifted in childhood, and finally in those with which he was gifted in infancy; and then he is a "little child," of whom the Lord said that "of such is the kingdom of God." This implantation is effected by the Lord alone; and for this reason nothing celestial is possible with man, nor can be, that is not from the Lord, and that is not the Lord’s.
 But the Lord from His own power conjoined His external man with His internal man, and filled His knowledges with celestial things, and implanted them in the celestial things, and this in fact according to Divine order; first in the celestial things of His childhood, next in the celestial things of the age between childhood and infancy; and finally in the celestial things of His infancy; and thus at the same time became, as to the Human Essence, innocence itself and love itself, from which are all innocence and all love in the heavens and on earth. Such innocence is true infancy, because it is at the same time wisdom. But the innocence of infancy, unless by means of knowledges it becomes the innocence of wisdom, is of no use; and therefore in the other life infants are imbued with knowledges. As the Lord implanted knowledges in celestial things, so had He perception, for, as before said, all perception is from conjunction. He had His first perception when He implanted the memory-knowledges of childhood, which perception is signified by "the oak-grove of Moreh;" and His second, treated of here, which is more internal, when He implanted knowledges, which perception is signified by "the oak-groves of Mamre that are in Hebron."
AC 1617. That this is the sixth state, is evident from the things contained in the preceding chapter.
AC 1618. And there he built an altar to Jehovah. That this signifies worship from that state, is evident from the signification of "an altar," as being a representative of all worship in general (n. 921). By worship, in the internal sense, is meant all conjunction through love and charity. When a man is in love and charity he is continually in worship, external worship being merely the effect. The angels are in such worship; with them, therefore, there is a perpetual Sabbath; and from this the Sabbath, in the internal sense, signifies the Lord‘s kingdom. But man, while in the world, ought not to be otherwise than in external worship also; for by external worship internal things are excited, and by means of external worship external things are kept in holiness, so that internal things can flow in. And besides, man is thus imbued with knowledges, and is prepared for receiving celestial things, and is also gifted with states of holiness, although he is unaware of this; which states of holiness are preserved to him by the Lord for the use of eternal life, for in the other life all the states of his life return.
