3116. These three verses deal with the investigation of truth that was to be introduced into good and so joined to it, in particular as regards its origin, for every single thing is dependent on its origin. Derivations take shape from their origin as their own root or seed in the way that a young plant does from its root or seed. These things residing with Him the Lord saw and investigated from the Divine, and from His own wisdom and intelligence introduced them, that is to say, introduced truths into the good of the rational. It is the investigation itself that is described in these verses in the internal sense; yet the things present in that sense can be explained to very few.

[2] Investigation also takes place with everyone who is being reformed, also with anyone who receives remnants. But of this investigation man knows nothing at all. To him it is so shrouded in obscurity that he does not even believe that it exists, even though it is taking place moment by moment. The Lord however, who alone has sight of a person's state, not only as it is at present but also as it will be for ever, is the one who carries out that investigation. Investigation involves a very delicate balancing to prevent even the smallest amount of falsity being joined to good, or the least amount of truth to evil. If falsity were joined to good, or truth to evil, a person would perish for ever, for he would in that case be suspended in the next life between hell and heaven, ejected by hell on account of good, and by heaven on account of evil.

9656. 'And they shall be paired from below, and at the same time paired up to its head' means a joining together from without and from within. This is clear from the meaning of 'being paired' as being made to act jointly; from the meaning of 'from below' as from without, since the Word portrays what exists outwardly as that which is below, and what exists inwardly as that which is above, 3084, 4599, 5146, 8325 (so that things deep down are more outward and those high up more inward, 2148, 4210, 4599); and from the meaning of 'the head', in the expression 'from below up to the head', as from within. The reason why 'the head' has this meaning is that the head is above the body, and by things above are meant those that are inward, as has just been stated; and in addition to this a person's inward powers are located in the head, for in it reside the beginnings of the senses and motions, and the beginnings are inmost because they are the source from which everything else flows. These beginnings are like wellsprings from which streams of water flow.

[2] This also goes to explain why inward things are portrayed in the Word as 'the head', as in Isaiah,

Jehovah will cut off from Israel head and tail, the branch and the bulrush in one day. Isaiah 9:14.

In the same prophet,

There will not be for Egypt [any] work which the head and tail, branch and bulrush will do. Isaiah 19:15.

This refers to the Church, the inward things of which are 'the head' and the outward ones 'the tail'.

[3] In the same prophet,

On all heads there is baldness; every beard is shaved off. Isaiah 15:2.

'Baldness on heads' stands for the absence of good and truth in inward things, 'beard shaved off' for the absence of good and truth in outward things. In Jeremiah,

You will be put to shame by Egypt, as you were put to shame by Asshur, and your hands will be on your head. For Jehovah has loathed your defences. Jeremiah 2:36-37.

This describes shame on account of the loss of the Church's forms of good and its truths, brought about by factual knowledge and by reasonings based on it, 'Egypt' being factual knowledge and 'Asshur' reasoning based on it. 'Hands on head' stands for covering over inward things owing to shame. Something similar occurs elsewhere in the same prophet,

They were put to shame and subjected to ignominy, and they covered their heads. Jeremiah 14:3-4; 2 Samuel 13:19.
