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.

1813. 'He reckoned it to him as righteousness' means that in this the Lord first became righteousness. This too becomes clear from the train of thought in the internal sense, in which the Lord is the subject. That the Lord alone became righteousness for the sake of the whole human race becomes clear from the consideration that He alone has fought out of Divine Love, that is to say, out of love towards the whole human race, whose salvation, that and nothing else, He desired and longed for in His conflicts. The Lord was not born righteousness as regards the Human Essence but became righteousness through the conflicts brought about by temptations and through victories, something He achieved by His own power. And as often as He fought and won the victory, this was reckoned to Him as righteousness, that is, it was added to the righteousness He was becoming, as an increase to it every time, until He became perfect righteousness.

[2] When one who is begotten from a human father, that is, from the seed of a human father, fights for himself, he cannot possibly do so out of any other love than love of self and love of the world, thus not out of heavenly love but out of hellish, for such is the nature of the proprium he possesses from his father in addition to the proprium he has acquired by his own actions. Consequently the person who imagines that he fights the devil from himself is grossly mistaken. So too the person who wishes to make himself righteous by his own powers, that is, to believe that the goods of charity and the truths of faith come from himself, and consequently to merit heaven through them, is acting and thinking contrary to the good and truth of faith. For it is a truth of faith, that is, it is the truth itself, that the Lord is the one who does battle. Thus because he is acting and thinking contrary to a truth of faith, he deprives the Lord of what is His and makes what is the Lord's his own; or what amounts to the same, he replaces the Lord with himself and so with that in himself which is from hell. It is for this reason that people wish to become great or the greatest in heaven, and thus it is that they believe quite wrongly that the Lord fought against the hells so that He might be the greatest. The human proprium has delusions such as these within it which have all the appearance of being truths but which are quite the reverse.

[3] That the Lord came into the world so as to become righteousness, and that He alone is righteousness, was also foretold by the Prophets. Thus it was possible to know of this even before His Coming, and also to know that He could not become righteousness except by means of temptations and victories over all evils and over all the hells, as in Jeremiah,

In His days Judah will be saved, and Israel will dwell with confidence. And this is His name which they will call Him. Jehovah our Righteousness. Jeremiah 23:6.

In the same prophet,

In those days and at that time I will cause a shoot of righteousness to sprout forth for David, and he will execute judgement and righteousness in the land. In those days Judah will be saved and Jerusalem will dwell with confidence. And this is what they will call Him, Jehovah our Righteousness. Jeremiah 33:15-16.

In Isaiah,

He saw and there was no man, and wondered that there was no intercessor, and His own arm brought salvation to Him, and His righteousness upheld Him. And He put on righteousness as a breastplate, and a helmet of salvation upon His head. Isaiah 59:16-17.

And see especially Isaiah 63:3, 5. 'His own arm' stands for His own power. Since the Lord alone is righteousness, the expression a habitation of righteousness is also used, in Jeremiah 31:23; 50:7.
