3365. And Isaac went unto Abimelech king of the Philistines, unto Gerar. That this signifies the doctrinal things of faith, is evident from the representation of Isaac, as being the Lord as to the Divine rational (see above, n. 1893, 2066, 2072, 2083, 2630; and that “Isaac” is the Lord’s Divine rational as to Divine good, n. 3012, 3194, 3210; and also as to Divine truth, which is represented by the marriage of Isaac with Rebekah, n. 3012, 3013, 3077); thus by Isaac is here represented the Lord as to Divine truth conjoined with the Divine good of the rational; for Rebekah was with Isaac, and was called “sister;” from the representation of Abimelech, as being the doctrine of faith that looks to rational things (n. 2504, 2509, 2510, 2530); and from the signification of the “king of the Philistines,” as being doctrinal things (that in the internal sense a “king” denotes the truth which is of doctrine, may be seen above, n. 1672, 2015, 2069; and that the “Philistines” signify the memory-knowledge of knowledges, which also is that of doctrinal things, n. 1197, 1198); and from the signification of “Gerar,” as being faith (n. 1209, 2504).

This shows what is signified by Isaac’s going to Abimelech king of the Philistines, unto Gerar, namely, that from the Lord comes the doctrine of faith that looks to rational things; or what is the same, the doctrinal things of faith. All those things are called doctrinal which are of doctrine, and which insofar as they can be received and acknowledged in heaven by angels, and on earth by men, are said to look to rational things, for it is the rational that receives and acknowledges them. But the rational is such that it cannot possibly apprehend Divine things, for it is finite, and the finite cannot apprehend what is of the infinite; and consequently truths Divine from the Lord are presented before the rational by means of appearances. Hence it is that doctrinal things are nothing but appearances of truth Divine, that is, nothing but celestial and spiritual vessels, within which is what is Divine; and because the Divine, that is, the Lord, is in them, they affect us, whence comes the conjunction of the Lord with angels and men.

2066. And I will give thee a son from her also. That this signifies the rational, is evident from the signification of a “son,” as being truth (see n. 489, 491, 533, 1147); and as all that is rational begins from truth, the rational is here signified by a “son.” The Lord’s first rational was represented and signified by Ishmael, born of Hagar the handmaid treated of in the preceding chapter 16. . The second rational, treated of here, is represented and signified by Isaac who was to be born from Sarah. The former, that is, the rational represented by Ishmael, was the rational that was afterwards expelled from the house; but this second rational, represented by Isaac, is that which remained in the house, because it was Divine. But concerning this rational, of the Lord’s Divine mercy we shall speak in the following chapter, where Isaac is treated of.
