2652. 'The son of Hagar the Egyptian' means into the merely human rational, 'Hagar the Egyptian' being the affection for knowledge, from which affection as its mother that rational was born. This is clear from the meaning of 'the son', who was Ishmael, as the first rational which the Lord had, dealt with in Chapter 16, where Hagar and Ishmael are the subject, and from his representation and that of Hagar the Egyptian who was his mother, also dealt with in that chapter. As regards the first or merely human rational with the Lord being conceived from the Divine celestial as a father, and being born from the affection for knowledge as a mother, see 1895, 1896, 1902, 1910.
