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.

489. That by “sons and daughters” are signified the truths and goods which they had a perception of, and indeed by “sons” truths, and by “daughters” goods, is evident from many passages in the Prophets; for in the Word, as also in olden time, the conceptions and births of the church are called “sons and daughters” as in Isaiah:

The Gentiles shall come to thy light, and kings to the brightness of thy rising; lift up thine eyes round about and see; all they gather themselves together and come to thee; thy sons shall come from far, and thy daughters shall be nursed at thy side; then thou shalt see and flow together, and thy heart shall be amazed, and shall be enlarged (Isaiah 60:3-5),

in which passage “sons” signify truths, and “daughters” goods.

[2] In David:

Deliver me and rescue me from the hand of the sons of the stranger, whose mouth speaketh vanity; that our sons may be as plants grown up in their youth, that our daughters may be as corner-stones hewn in the form of a temple (Psalms 44:11-12),

where the “sons of the stranger” signify spurious truths, or falsities; “our sons” signify doctrinals of truth; “our daughters” doctrinals of good.

[3] In Isaiah:

I will say to the north, Give up, and to the south, Keep not back; bring My sons from far, and My daughters from the ends of the earth; bring forth the blind people, and they shall have eyes; the deaf, and they shall have ears (Isaiah 43:6, 8),

in which passage “sons” signify truths; “daughters” goods; the “blind” those who would see truths; and the “deaf” those who would obey them.

[4] In Jeremiah:

Shame hath devoured the labor of our fathers from our youth; their flocks, their herds, their sons, and their daughters (Jeremiah 3:24),

where “sons” and “daughters” signify truths and goods. That “children” and “sons” signify truths, is plain from Isaiah: Jacob shall not now be ashamed, neither shall his face now wax pale; for when he shall see his children the work of My hands in the midst of him, they shall sanctify My name, and shall sanctify the Holy One of Jacob, and shall fear the God of Israel; they also that erred in spirit shall know understanding (Isaiah 29:22-24,

where the “Holy One of Jacob, the God of Israel” signifies the Lord; “children” signify the regenerate, who have the understanding of good and truth, as is indeed explained.

[5] Again:

Sing, O barren, thou that didst not bear, for more are the sons of the desolate than the sons of the married wife (Isaiah 54:1),

where the “sons of the desolate” signify the truths of the primitive Church, or that of the Gentiles; the “sons of the married wife” the truths of the Jewish Church.

[6] In, Jeremiah:

My tent is laid waste and all My cords are plucked out; My sons are gone forth of Me, and are not (Jeremiah 10:20),

where “sons” signify truths. Again:

His sons shall be as aforetime, and their congregation shall be established before Me (Jeremiah 30:20),

where “sons” signify the truths of the Ancient Church.

In Zechariah:

I will stir up thy sons, O Zion, with thy sons, O Javan, and make thee as the sword of a mighty man (Zechariah 9:13),

signifying the truths of the faith of love.
