2719. In this chapter the Lord's rational has first been treated of, as being made Divine, which rational is "Isaac;" then the merely human rational, as being separated, which is the "son of Hagar the Egyptian;" and afterwards the spiritual church, which was saved by the Lord's Divine Human, which church is "Hagar" and her "child." Now the doctrine of faith is treated of, which is to be serviceable to that church; namely, that human reasonings from memory-knowledges are adjoined to it, which are "Abimelech" and "Phicol." This conjunction is signified by the "covenant" which Abraham made with them. These reasonings are appearances, not from a Divine but from a human origin, which are adjoined for the reason that without them the spiritual church would not comprehend doctrine, and thus would not receive it. For, as was shown above (n. 2715), the man of the spiritual church is relatively in obscurity; and doctrine is therefore to be clothed with such appearances as are of human thought and affection, and is not to be in discrepancy to such a degree that the Divine good cannot have in them some kind of receptacle. As Abimelech is again treated of in the following twenty-sixth chapter, and also a covenant (but with Isaac); and in the internal sense, the reasonings and memory-knowledges added to the doctrine of faith a second time, only a summary may here be given of the things contained in the internal sense, which will become clearer by the explication of that chapter.
