Arcana Coelestia #2507
2507. Of Sarah his wife. That this signifies spiritual truth conjoined with the celestial, is evident from the signification of “Sarah” as a wife, as being intellectual truth conjoined with the Divine good, or what is the same, spiritual truth conjoined with the celestial (see n. 1468, 1901, 2063, 2065, 2172, 2173, 2198). What the spiritual is, and what the celestial, has often been stated before (see n. 1155, 1577, 1824, 2048, 2088). That is called Celestial, which is of good, that is, which is of love to the Lord and of charity toward the neighbor; and that Spiritual, which is of truth, that is, which is of faith derived from those loves.
Arcana Coelestia #1468
1468. He said to Sarai his wife. That this signifies that He so thought concerning the truths to which celestial things were adjoined, is evident from the signification of Sarai when she is called a wife. A “wife,” in the internal sense of the Word, signifies nothing else than truth conjoined with good; for the conjunction of truth with good is circumstanced precisely as is a marriage. In the Word, when a “husband” is mentioned, the husband signifies good, and the wife signifies truth; but when he is not called the husband, but the “man,” then he signifies truth, and the wife signifies good: this is the constant usage in the Word, as before said n. 915). In the passage before us, as Abram is named, Sarai his wife signifies truth. To say thus to Sarai his wife is, in the internal sense, to think so concerning the truths with which celestial things were conjoined. It is historically true that Abram so said to his wife, when journeying into Egypt; but as before said, all the historicals of the Word are representative, and all the words are significative. No other historicals are recorded in the Word, and in no other order, and no other words are used to express them, than such as in the internal sense may express these arcana.
