2637. 'When Isaac his son was born to him' means when the Lord's Rational was made Divine. This is clear from the meaning of 'being born' as being manifested, dealt with in 2584, 2621, 2629, and from the representation of 'Isaac' as the Divine Rational, dealt with in 2630. The latter is said 'to be born' to Abraham when it has been made Divine, as also in verse 3 above, 'Abraham called the name of his son born to him', see 2628.

2628. 'Abraham called the name of his son born to him' means the nature of the Rational was such that it was Divine. This is clear from the representation of 'Abraham' as the Lord as regards the Divine celestial or Divine Good, dealt with many times already; from the meaning of 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009; and from the meaning of 'a son' as the rational, dealt with in 2623, as well as from the meaning of 'born to him' as being manifested from the Divine. From this it is evident that 'Abraham called the name of his son born to him' means that the nature of the Rational was such that it was Divine. From these few words the following three arcana shine through to those who possess the internal sense. The first is that the Lord's Divine Human was a manifestation from the Divine itself, an arcanum which is explained further in this verse; the second is that the Lord's Divine Human was not only conceived but also born from Jehovah, and therefore the Lord as regards the Divine Human is called the Son of God and the Only Begotten, John 1:14, 18, 49; 3:16, 18, 35-36; 5:19-27; 6:69; 9:35; 10:36; 11:27; 14:13-14; 17:1; 20:31; and similarly in the other Evangelists; and the third arcanum is that the Lord's Divine Human is meant by the name of Jehovah, that is, His nature, see John 12:28.
