35. 28 shows that the Old Testament prophets represented the Lord in respect to the Word and therefore meant the teaching of the church drawn from the Word, and that because of this they were addressed as “children of humanity.” It follows from this that by the various things they suffered and endured they represented the violence done to the literal meaning of the Word by Jews. Isaiah, for example, took the sackcloth off his waist and the sandals off his feet and went naked and barefoot for three years (Isaiah 20:2-3). Similarly, Ezekiel the prophet took a barber’s razor to his head and his beard, burned a third of the hair in the middle of the city, struck a third with a sword, and scattered a third to the wind; also, he bound a few hairs in his hems and eventually threw a few into the midst of a fire and burned them (Ezekiel 5:1-4).
Since the prophets represented the Word and therefore meant the teaching of the church drawn from the Word (as just noted), and since the head means wisdom from the Word, the hair and the beard mean the outermost form of truth. It is because of this meaning that inflicting baldness on yourself was a sign of immense grief and being discovered to be bald was an immense disgrace. This and this alone is why the prophet shaved off his hair and his beard - to represent the state of the Jewish church in regard to the Word. This and this alone is why two she-bears tore apart forty-two boys who called Elisha bald (2 Kings 2:23-25)-because as just noted the prophet represented the Word, and his baldness signified the Word without an outermost meaning.
We shall see in §49 below that the Nazirites represented the Lord’s Word in its outermost forms, which is why they were commanded to let their hair grow and not to shave any of it. In Hebrew, “Nazirite” actually means “hair.” It was commanded also that the high priest was not to shave his head (Leviticus 21:10) and that the fathers of their families as well were not to do so (Leviticus 21:5).
That is why they regarded baldness as such an immense disgrace, as we can tell from the following passages:
There will be baldness upon all heads, and every beard will be cut off. (Isaiah 15:2; Jeremiah 48:37)
There will be shame upon all faces and baldness on all heads. (Ezekiel 7:18)
Every head was made bald and every shoulder hairless. (Ezekiel 29:18)
I will put sackcloth around all waists and baldness upon every head. (Amos 8:10)
Make yourself bald and cut off your hair because of your precious children; make yourself still more bald, because they have left you and gone into exile. (Micah 1:16)
Here making yourself bald and making yourself still more bald means distorting truths of the Word in its outermost forms. Once they have been distorted, as was done by Jews, the whole Word is ruined, because the outermost forms of the Word are what it rests on and what holds it up. In fact, every word in it is a base and support for the Word’s heavenly and spiritual truths.
Since a head of hair means truth in its outermost forms, in the spiritual world everyone who trivializes the Word and distorts its literal meaning looks bald; but those who respect and love it have good-looking hair. On this, see §49 below.

468. And his feet like pillars of fire. This symbolizes the Lord's Divinity on the natural plane in respect to His Divine love, which sustains all things.
This, too, is apparent, from the explanation in no. 49 above, where it is said of the Son of Man that "His feet were like fine brass, as though fired in a furnace."
The angel's feet looked like pillars of fire because the Lord's Divinity on the natural plane - which fundamentally is the Divine humanity that He took on in the world - supports His Divinity from eternity, as the body does the soul, and likewise as the Word's natural meaning supports its spiritual and celestial meanings, on which subject see The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos.27-49. To be shown that feet symbolize something natural, see no. 49, and a pillar something that supports, no. 191.
Fire symbolizes love because spiritual fire is nothing else. Therefore it is customary in worship to pray that heavenly fire, that is to say, heavenly love, may kindle the worshipers' hearts. People know that there is a correspondence between fire and love from the fact that a person grows warm with love, and cold with its loss. Nothing else produces vital warmth but love, in both senses. The origin of these correspondences is owing to the existence of two suns, one in the heavens, which is pure love, and the other in the world, which is nothing but fire. This, too, is the reason for the correspondence between all spiritual and natural things.
 Since fire symbolizes Divine love, therefore on Mount Horeb Jehovah appeared to Moses in a bush on fire (Exodus 3:1-3). Moreover He descended upon Mount Sinai in fire (Deuteronomy 4:36). For this reason, too, the seven lamps of the lampstand in the Tabernacle were lit every evening, so as to burn before Jehovah (Leviticus 24:2-4). For the same reason fire burned continually on the altar and was not extinguished (Leviticus 6:13), and the priests took fire from the altar in their censers and burned incense (Leviticus 16:12-13).
Therefore Jehovah went before the children of Israel by night in a pillar of fire (Exodus 13:21-22). Fire from heaven consumed the burnt offerings on the altar, as a sign of His being well pleased (Leviticus 9:24, 1 Kings 18:38). The burnt offerings were called offerings by fire to Jehovah, and offerings by fire for a restful aroma to Jehovah (Exodus 29:18; Leviticus 1:9, 13, 17; 2:2, 9-11; 3:5, 16; 4:35; 5:12; 7:30; 21:6; Numbers 28:2; Deuteronomy 18:1).
Therefore in the book of Revelation the Lord's eyes looked like a flame of fire (Revelation 1:14; 2:18; 19:12, cf. Daniel 10:5-6). And seven lamps of fire burned before the throne (Revelation 4:5).
It is apparent from this what lamps containing oil and lamps without oil symbolize (Matthew 25:1-11). The oil means fire, and thus love.
And so on in many other places.
In an opposite sense fire symbolizes hellish love, and this is plain from so many passages in the Word that it would be impossible to cite them all because of their number. See something on the subject in the book Heaven and Hell, published in London, nos. 566-575.
