Arcana Coelestia #2008
2008. Verse 5 And no longer will your name be called Abram, but your name will be Abraham, for I have made you the father of a multitude of nations.
'No longer will your name be called Abram' means that He will cast off the human. 'But your name will be Abraham' means that He will put on the Divine. 'For I have made you the father of a multitude of nations' means here, as previously, that from Him comes all truth and resulting good.
Genesis 17:25

Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin.
