3373. And unto thy seed. That this signifies truth, is evident from the signification of “seed,” as being truth (see n. 29, 255, 1025, 1447, 1610, 1940, 2848, 3310); thus it signifies the truth which is from the Lord’s Divine, which is “thy seed.” They who apprehend the Word only according to the sense of the letter cannot know but that “seed” denotes posterity, consequently here the posterity of Isaac from Esau and Jacob, and chiefly from Jacob, because the Word was in that nation and it contains so many historical facts concerning them. But in the internal sense by “seed” there is not meant any posterity from Isaac, but all those who are sons of the Lord, thus the sons of His kingdom, or what is the same, who are in good and truth from the Lord; and because these are “seed,” it follows that the very good and truth from the Lord are “seed,” for hence come the sons; wherefore also the very truths from the Lord are called the “sons of the kingdom,” in Matthew:

He that soweth the good seed is the Son of man; the field is the world; the good seed are the sons of the kingdom (Matthew 13:37-38);

hence also by “sons” in general are signified truths (n. 489, 491, 533, 1147, 2623).

[2] Everyone who thinks somewhat more deeply or interiorly may know that in the Divine Word by the “seed of Abraham, of Isaac, and of Jacob,” so often mentioned, and concerning which it is so frequently said that it should be blessed, and this above all nations and people in the world, cannot be signified their posterity; for above all nations they were least of all in the good of love to the Lord and of charity toward the neighbor, and were not even in any truth of faith; for they were utterly ignorant of what the Lord is, what His kingdom, thus what heaven is, and what the life after death, both because they did not want to know, and because if they had learned about these things, they would at heart have totally denied them, and would thus have profaned interior goods and truths, just as they so frequently profaned exterior ones by becoming open idolaters; which is the reason why in the sense of the letter of the Word of the Old Testament any interior things so rarely stand forth to view. Being of this nature, the Lord has said concerning them, quoting Isaiah:

He hath blinded their eyes, and hardened their heart, lest they should see with their eyes and understand with their heart, and should be converted, and I should heal them (John 12:40);

and again when they said:

We are Abraham’s seed; Abraham is our father; Jesus said unto them, If ye were Abraham’s sons, ye would do the works of Abraham; ye are of your father the devil, and the desires of your father ye will to do (John 8:33, 39, 44);

by “Abraham” here is meant the Lord, as everywhere in the Word; and that the Jews were not his seed, or sons, but the seed of the devil, is plainly stated. All this shows very plainly that by the “seed of Abraham, of Isaac, and of Jacob” as mentioned in the historical and prophetical Word, are by no means meant their posterity-for the Word throughout is Divine-but all those who are the Lord’s “seed,” that is, who are in the good and truth of faith in Him. (That from the Lord alone comes heavenly seed, that is, all good and truth, may be seen above n. 1438, 1614, 2016, 2803, 2882-2883, 2891, 2892, 2904, 3195)

3023. I will make thee swear by Jehovah the God of heaven and the God of the earth. That this signifies a most holy pledging to the Divine which is in the highest and in that which is therefrom, is evident from the signification of “causing to swear,” as being to pledge by oath; for to cause to swear is nothing else than to pledge; and this is most holy when it is by Jehovah the God of heaven and the God of the earth, that is, to the Divine which is above and which is beneath, or what is the same, to the Divine which is in the highest and in that which is therefrom. “Jehovah the God of heaven,” being said of the Lord, denotes Jehovah Himself who is called the Father, from whom He was conceived, thus who was His Divine Essence; for the conception itself gave the veriest essence from which He was. “Jehovah the God of the earth” in this case means Jehovah who is called the Son, thus His Human essence; this came forth from the Divine essence when the Lord made it also Divine. Thus by “Jehovah the God of heaven” is signified the Divine that is in the highest; and by “Jehovah the God of the earth” is signified the Divine that is in that which is therefrom. But the Lord is called “Jehovah the God of heaven” from His Divine that is in the heavens; and He is called the “God of the earth” from His Divine that is on earth. The Divine in the heavens is also that which is with man in his internals; but the Divine on earth is that which is in his externals; for the internals of man are his heaven, because by them he is conjoined with the angels; but his externals are his earth, for by them he is conjoined with men (n. 82, 913, 1411, 1733). When a man is regenerate, the internals flow into the externals, and the externals are from the internals. Hence also it may be known what the internals of the church are, and what its externals.
