The same things are signified by “sons” and “daughters” in this chapter (verses 4, 7, 10, 13, 16, 19, 26, 30), but such as is the church, such are the “sons and daughters” that is, such are the goods and truths; the truths and goods here spoken of are such as were distinctly perceived, because they are predicated of the Most Ancient Church, the principal and parent of all the other and succeeding churches.

2971. The field and the cave that was therein. That this signifies as to the good and the truth of faith, is evident from the signification of “field” as being the church, also the good itself of the church. The celestial, or good, which is of love to the Lord and of charity toward the neighbor, is compared to “ground,” and also to “field;” it is also called “ground” and “field;” because the celestial or good is that which receives the truths of faith, which are compared to seeds and are also called “seeds.” The same is evident also from the signification of a “cave,” as being the truth of faith which is in obscurity (see n. 2935); it is said to be in obscurity because it is with the spiritual (see n. 1043, 2708, 2715).
