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.

3266. 'These are the names of the sons of Ishmael' means the essential characteristics of those people's forms of doctrine, that is to say, of those who are spiritual. This is clear from the meaning of 'name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, from the meaning of 'sons' as truths, and also matters of doctrine, dealt with in 489, 491, 533, 1147, 2623, and from the representation of 'Ishmael' as those who are spiritual, dealt with above in 3263.
