Arcana Coelestia # 2112
2112. Was Abraham circumcised, and Ishmael his son. That this signifies that when the Lord conjoined His Human Essence with His Divine Essence, He also conjoined with Himself all others who become rational from truth and saved them, is evident from the representation of Abraham in this chapter, as being the Lord in that state and at that age (see above, n. 1989); and from the representation of Ishmael here, as being those who become rational from truth (explained above, n. 2078, 2087, 2088); and also from the signification of “being circumcised,” as being to be purified (see above, n. 2039), and when predicated of the Lord, to be glorified, and thus to put off the human and to put on the Divine. (That to be glorified is to put on the Divine, may be seen above, n. 2033; and that the Lord then conjoined with Himself those who become rational from truth, that is, the spiritual, may also be seen above, n. 2034, 2078, 2088)
Arcana Coelestia # 2087
2087. As for Ishmael, I have heard thee. That this signifies those who are rational from truth, that they are to be saved, is evident from the representation of Ishmael in this place, as being those who are rational from truth, or the spiritual (spoken of above, n. 2078); and that they are to be saved, is evident from the signification of “hearing thee,” as may be seen without explication.
