Arcana Coelestia # 62
62. The stages and states of the regeneration of man - both of mankind and of the individual person - divide into six and are called the days of his creation. Gradually from being no man at all, he first becomes something, though only little, then something more, until the sixth day is reached, when he becomes 'an image'.
Arcana Coelestia # 2110
2110. 'When he was circumcised in the flesh of his foreskin' means purification. This is clear from the meaning of 'being circumcised' as being purified from self-love and the love of the world, dealt with in 2039, and from the meaning of 'flesh of the foreskin' as the removal of those loves, dealt with in 2041, 2053, 2057.
