2632. 'Abraham circumcised his son Isaac' means purification of the rational. This is clear from the meaning of 'being circumcised' as being purified, dealt with in 2039, and from the representation of 'Isaac' as the Divine Rational, dealt with in 2630.

[2] The Lord's first rational was born in the way it is with others, that is to say, by means of facts and cognitions. This has been stated already where Ishmael, who represents that rational, is the subject. Because it was born, as with others, by means of facts and cognitions, thus by the external way, which is that of the senses, this rational inevitably included many things that were worldly in origin, for it is from those things that the ideas which the rational possesses are acquired. This was even more so the case with the Lord on account of the heredity He had from the mother. It was those worldly things and this heredity which the Lord gradually cast out of His rational until it was such that it was able to receive the Divine, 2624, 2625. At this point the Lord's Divine Rational, represented by 'Isaac', was born, 2630, not indeed by the external way, which is that of the senses - as was the case with the previous rational - but by the internal way from the Divine itself, 2628, 2629. As this was not accomplished all at once but gradually, 1690, 2033, the rational was purified, and constantly so. It is this purification that is meant by 'Abraham circumcised his son, a son eight days old'. That the Lord gradually made His Rational Divine and purified it constantly is clear also in John,

Jesus said, Father, glorify Your name. A voice therefore came from heaven, I have both glorified it, and will glorify it again. John 12:28.

'Glorifying' is making Divine, see 1603, 1999.

[3] In the Ancient Church nothing else was represented and meant by circumcision than that a person should be purified from self-love and love of the world, which is also effected gradually and constantly, see 2039, 2046 (end), 2049, 2056, especially when a person has been born anew or regenerated. For at that time the Lord is flowing in by the internal way, that is, through the good that forms part of conscience; and He gradually and constantly separates the things which cling to that person both as a result of hereditary evil and of the evil of his own doing.

2046. 'Every male' means those who possess the truth of faith. This is clear from the meaning of 'a male' as truth, dealt with in 672, 749. The reason why the word 'male', meaning the truth of faith, is used is that nobody can be purified from those filthy loves except the person who is governed by truth. From truth he recognizes what is pure or impure, and what is holy or unholy. Until he possesses such knowledge there are no channels into which and through which heavenly love flowing in constantly from the Lord is able to operate, for it cannot be received except within truths. It is by means of cognitions of truth therefore that a person is reformed and regenerated, but this does not take place before he has been endowed with them. Conscience itself is formed by means of the truths of faith, for the conscience with which a regenerate person is endowed is a conscience for what is true and right. On this matter see 977, 986 (end), 1033, 1076, 1077. This also is the reason why flint knives, or 'swords of flint', as they are called, were used for circumcision. 'Swords of flint' means truths, see above 2039 (end).
