3194. Isaac came from coming from [or to] Beer-lahai-roi. That this signifies Divine good rational born from Divine truth itself, is evident from the representation of Isaac, as being the Lord’s Divine rational (see n. 2083, 2630); here, as to the Divine good therein, because Divine truth called forth out of the natural (which Divine truth is represented by Rebekah) was not as yet conjoined with good; this conjunction is treated of in the verses which follow; and also from the signification of “to come from coming from Beer-lahai-roi,” as denoting to be born from Divine truth; Beer-lahai-roi in the original tongue signifies “the fountain to the Living One that seeth me;” as above (Genesis 16:13-14) where we read:

Hagar called the name of Jehovah that was speaking unto her, “Thou art the God that seeth me; for she said, Have I also here seen after Him that seeth me? Therefore she called the fountain Beer-lahai-roi (the fountain to the Living One that seeth me).

What is signified by these words may be seen above (n. 1952); where also it is evident that the “fountain” is Divine truth; and that the “Living One that seeth me” is Divine good rational, which is there called the Lord’s interior man, from Divine truth. The case in regard to this very deep arcanum is this: The veriest Divine has Good and Truth; the Lord as to the Divine Human came forth from the Divine good, and was born of the Divine truth; or what is the same, the very esse [or being] of the Lord was Divine good, and the very existere [or manifestation] was Divine truth; and this was the source of the Lord’s Divine good rational, with which He conjoined the Divine truth from the Human.

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.
