436. And they had breastplates like breastplates of iron. (9:9) This symbolically means that their arguments based on fallacies, with which they battled and prevailed, appeared to them too strong to be refuted.

Breastplates symbolize protections, because they protect the breast. Here they symbolize protections of falsities, which are concocted by arguments based on fallacies, which people use to defend a false proposition. For from a false proposition nothing but falsities can flow. If truths are advanced, they are regarded only externally or superficially, thus also sensually, and so are falsified, becoming then fallacies in the people who entertain them.

Breastplates have this symbolism because battles in the Word symbolize spiritual battles, and weapons of war therefore symbolize various defenses connected with such a battle - as in Jeremiah,

Harness the horses, and mount up, you horsemen! And station yourselves in your helmets, polish the spears, put on the cuirass. (Jeremiah 46:4)

In Isaiah,

He put on righteousness as a breastplate, and a helmet of salvation on His head. (Isaiah 59:17)

In the book of Psalms,

...under His wings you shall be confident; His truth shall be your shield and buckler. (Psalms 91:4)

And so also elsewhere, as Ezekiel 23:24; 38:4; 39:9, Nahum 2:3, Psalm. 5:12; 35:2-3.

Their breastplates being breastplates of iron means, symbolically, that their arguments seemed to them too strong to be refuted; for owing to its hardness iron symbolizes strength.

49. We have so far shown that the Word in its natural sense, the literal sense, is in its holiness and in its fullness. We must now say something about the Word’s being in that sense present also in its power.

The magnitude and nature of the power of Divine truth in heaven, as well as on earth, can be seen from what we said in the book Heaven and Hell 228-233, about the power angels have in heaven.

The power of Divine truth is especially a power against falsities and evils, thus against the hells. One must fight against these by means of truths from the Word’s literal sense. It is also by means of the truths a person has that the Lord has the power to save him. For a person is reformed and regenerated by means of truths drawn from the Word’s literal sense, and he is then released from hell and introduced into heaven. This power is one that the Lord took on also in respect to His Divine humanity, after He had fulfilled everything in the Word, even to its outmost expressions. [2] That is why, when the Lord was about to fulfill the last of these by His suffering of the cross, He said to the chief priest,

“...hereafter you will see the Son of man sitting at the right hand of the Power, coming on the clouds of heaven.” (Matthew 26:64, cf. Mark 14:62)

The Son of man is the Lord in relation to the Word. The clouds of heaven are the Word in its literal sense. Sitting at the right hand of God (as also in Mark 16:19) is omnipotence exercised by means of the Word.

The Lord’s power emanating from the outmost expressions of the Word was represented in the Jewish Church by Nazirites, and by Samson, of whom we are told that he was a Nazirite from his mother’s womb, and that his power lay in his hair. Nazirite or the state of being a Nazirite also means a person’s hair.

[3] That Samson’s power lay in his hair, he himself declared, saying,

No razor has come upon my head, for I have been a Nazirite...from my mother’s womb. If I am shaven, then my strength will leave me, and I shall become weak, and be like any other man. (Judges 16:17)

It is impossible for anyone to know why the vow of a Nazirite, which means a person’s hair, was instituted, and why it is that Samson drew his power from his hair, unless he knows what the head symbolizes in the Word. The head symbolizes the wisdom of heaven, which angels and people have from the Lord by means of Divine truth. Therefore the hair of the head symbolizes the wisdom of heaven in outmost expressions, and also Divine truth in outmost expressions.

[4] Because this is the symbolic meaning of the hair by its correspondence with the heavens, therefore it was a statute for Nazirites that they not shave the hair of their heads, because it was the consecration of God upon their heads (Numbers 6:1-21). And for the same reason it was also a statute that the high priest and his sons not shave their heads, lest they die, and wrath come upon the whole house of Israel (Leviticus 10:6).

[5] Because the hair, on account of that symbolic meaning, which it had from its correspondence, was so holy, therefore the Son of man, that is, the Lord in relation to the Word, is described even in respect to His hair, that it was “like wool as white as snow” (Revelation 1:14). The Ancient of Days is described similarly (Daniel 7:9).

On this subject, see also something above in no. 35.

In sum, the power of Divine truth, or of the Word, lies in the literal sense, and that is because the Word is present there in its fullness, and because in that sense angels in both of the Lord’s kingdoms and people are together.
