157. Because 'bone from bones and flesh from flesh' meant the proprium belonging to the external man which contained the internal man, all who could be called one' s own were in ancient times called 'bone from bones and flesh from flesh', whether they came from the same house or from the same family, or had some other family connection, as Laban said of Jacob,
Surely you are my bone and my flesh. Genesis 29:14.
Referring to his mother's brothers and to 'the family of the house of his mother's father' Abimelech said,
Remember that I am your bone and your flesh. Judges 9:1-3.
Also the tribes of Israel, in reference to themselves, told David,
Behold, we are your bone and your flesh. 2 Samuel 5:1.

1960. That 'Hagar bore Abram a son' means the rational man born from that coming together and conception is clear from the representation and meaning of 'Hagar', 'Abram', and 'son'. 'Hagar' means the life which is present in the affection for knowledge and which belongs to the exterior man, as stated above in 1895, 1896; 'Abram' means the Lord's Internal Man, 1893, 1950; and 'a son' means truth, and so the truth which this rational possessed, 264, 489, 491, 533, 1147. Consequently the words 'Hagar bore for Abram' mean the rational man born from that conception and coming together. This is the sense into which the sense of the letter is converted when it comes to or resides with angels.
