2628. Abraham called the name of his son that was born unto him. That this signifies the quality of the rational as being Divine, is evident from the representation of Abraham, as being the Lord as to the Divine celestial, or the Divine Good, treated of many times before; and from the signification of "calling a name," as being the quality (see n. 144, 145, 1754, 1896, 2009); and from the signification of his "son," as being the rational (see n. 2623); and also from the signification of his being "born unto him," as being to come forth from the Divine. Hence it is evident that "Abraham called the name of his son that was born unto him," signifies the quality of the rational as being Divine.
From these few words three arcana shine forth for those who are in the internal sense: First, that the Lord's Divine Human came forth [exstiterit] from the Divine Itself; which is further treated of in this verse. Second, that the Lord's Divine Human was not only conceived, but also born, of Jehovah, and hence the Lord as to His Divine Human is called the "Son of God," and the "Only-begotten" (John 1:14, 18, 50; 3:16, 18, 35-36; 5:19-27; 6:69; 9:35; 10:36; 11:27; 14:13-14; 17:1; 20:31; and in like manner in the other Evangelists). Third, that the Lord's Divine Human is the "name" of Jehovah, that is, His quality (see John 12:28).
