3375. 'And I will fulfil the oath which I swore to Abraham your father' means confirmation. This is clear from the meaning of 'an oath' or 'swearing' as confirmation, dealt with in 2842. Here it does not say that the covenant made with Abraham is to be fulfilled but that 'the oath' will be. The reason for this is that 'a covenant' has reference to what is celestial, which is good, whereas 'an oath' has reference to what is spiritual, namely truths, see 3037; and truths are the subject here. For the same reason also in verse 31 below it is not said of Isaac that he made a covenant with Abimelech but that 'he swore to him, a man to his brother', whereas in Genesis 21:32 it is said of Abraham that he and Abimelech 'made a covenant'; see Psalms 105:9. By the confirmation here which is meant by 'an oath' is understood the Lord's being joined to those who are in His kingdom, for an oath is the confirmation of a covenant, and by 'a covenant' is meant being joined together, 665, 666, 1023, 1038, 1864, 1996, 2003, 2021.

2021. 'For an eternal covenant' means conjunction with these people. This is clear from the meaning of 'a covenant' as conjunction, dealt with already in 665, 666, 1023, 1038; and that this conjunction is with those called 'the seed' is clear from the fact of its coming immediately after a reference to that 'seed', and of its being a second mention in this verse of a covenant. Thus the first mention of 'a covenant' has reference to the union of Jehovah with the Human Essence, and the second to the conjunction with those who are 'the seed'. To allow a clearer idea of the union of the Lord's Divine Essence with the Human Essence and of the conjunction of the Lord with the human race by means of the faith that inheres in charity, let the term union here and from now on be used to describe the first of these, and conjunction the second. Indeed the bond between the Lord's Divine Essence and Human Essence really was a union, but that between the Lord and the human race by means of the faith that inheres in charity is conjunction. From this it is clear that because Jehovah or the Lord is Life, His Human Essence became Life as well, as shown above. It was a union of life with life. Man however is not life but a recipient of life, as also shown already. When life flows into a recipient of life conjunction takes place, for life accommodates itself to the recipient as active does to passive or as that which in itself is living does to that which in itself is dead but made living from that which in itself is living. In the case of the principal and the instrumental, as they are called, they do indeed seem to have been joined together to exist as one. Nevertheless they are not one, for each exists by itself. Man does not live of himself, but the Lord in His mercy links him to Himself and in so doing causes him to live for ever. And because the Lord and man are distinct and separate from each other the term conjunction is used.
