If the Long Hair is a covering

[Praxeas]

I do find it interesting, however, that when Samson fell, it was due to his hair being removed, not just trimmed. She shaved off the seven locks of his head.

It is an interesting question.

Num 6:1 And the LORD spoke unto Moses, saying,
Num 6:2 Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD:
Num 6:3 He shall separate himself from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried.
Num 6:4 All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk.
Num 6:5 All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth himself unto the LORD, he shall be holy, and shall let the locks of the hair of his head grow.
Num 6:6 All the days that he separateth himself unto the LORD he shall come at no dead body.
Num 6:7 He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head.
Num 6:8 All the days of his separation he is holy unto the LORD.
Num 6:9 And if any man die very suddenly by him, and he hath defiled the head of his consecration; then he shall shave his head in the day of his cleansing, on the seventh day shall he shave it.
Num 6:10 And on the eighth day he shall bring two turtles, or two young pigeons, to the priest, to the door of the tabernacle of the congregation:
Num 6:11 And the priest shall offer the one for a sin offering, and the other for a burnt offering, and make an atonement for him, for that he sinned by the dead, and shall hallow his head that same day.
Num 6:12 And he shall consecrate unto the LORD the days of his separation, and shall bring a lamb of the first year for a trespass offering: but the days that were before shall be lost, because his separation was defiled.
Num 6:13 And this is the law of the Nazarite, when the days of his separation are fulfilled: he shall be brought unto the door of the tabernacle of the congregation:
Num 6:14 And he shall offer his offering unto the LORD, one he lamb of the first year without blemish for a burnt offering, and one ewe lamb of the first year without blemish for a sin offering, and one ram without blemish for peace offerings,
Num 6:15 And a basket of unleavened bread, cakes of fine flour mingled with oil, and wafers of unleavened bread anointed with oil, and their meat offering, and their drink offerings.
Num 6:16 And the priest shall bring them before the LORD, and shall offer his sin offering, and his burnt offering:
Num 6:17 And he shall offer the ram for a sacrifice of peace offerings unto the LORD, with the basket of unleavened bread: the priest shall offer also his meat offering, and his drink offering.
Num 6:18 And the Nazarite shall shave the head of his separation at the door of the tabernacle of the congregation, and shall take the hair of the head of his separation, and put it in the fire which is under the sacrifice of the peace offerings.
Num 6:19 And the priest shall take the sodden shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put them upon the hands of the Nazarite, after the hair of his separation is shaven:
Num 6:20 And the priest shall wave them for a wave offering before the LORD: this is holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine.
Num 6:21 This is the law of the Nazarite who hath vowed, and of his offering unto the LORD for his separation, beside that that his hand shall get: according to the vow which he vowed, so he must do after the law of his separation.

Jdg 16:19 And she made him sleep upon her knees; and she called for a man, and she caused him to shave off the seven locks of his head; and she began to afflict him, and his strength went from him.

And I just discovered in doing a little search that the Nazarites weren't told not to put a razor to their hair, but to their heads. I think this is significant as it would suggest that putting a razor to their heads would indicate the removal of hair, not just the mere cutting of it.

It indicates their hair was uncut until the vow was fullfilled. This is how I was using the word. He was not to cut the hair at all, shaved, trimmed whatever. I was not trying to prove this word means "trimmed" I was showing it means cut...

Num 6:5 All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth himself unto the LORD, he shall be holy, and shall let the locks of the hair of his head grow.

Yes, notice "and shall let the locks of the hair of his head grow"...he was not to cut the hair at all, shaved, shorn, trimmed, cut...nothing it was to continue to grow untouched.

Of this text my NET bible commentary has an interesting note

14 sn There is an interesting parallel between this prohibition and the planting of trees. They could not be pruned or trimmed for three years, but allowed to grow free (Lev_20:23). Only then could the tree be cut and the fruit eaten. The natural condition was to be a sign that it was the Lord's. It was to be undisturbed by humans. Since the Nazirite was to be consecrated to the Lord, that meant his whole person, hair included. In the pagan world the trimming of the beard and the cutting of the hair was often a sign of devotion to some deity (see W. R. Smith, The Religion of the Semites, 327-35).

there shall no razor come upon his head; he might not shave his beard, nor cut off his locks, and shave his head, nor cut short his locks with a pair of scissors, nor any with anything by which the hair may be removed, as Ben Gersom; nor pluck off his hair with his hands, as Maimonides says (x); but let it grow as long as it would during the time of his separation, which is expressed in the latter part of the verse:

Keil and Deutsch
Secondly, during the whole term of his vow of consecration, no razor was to come upon his head. Till the days were fulfilled which he had consecrated to the Lord, he was to be holy, “to make great the free growth (see Lev_10:6) of the hair of his head.” The free growth of the hair is called, in Num_6:7, “the diadem of his God upon his head,” like the golden diadem upon the turban of the high priest (Exo_29:6), and the anointing oil upon the high priest's head (Lev_21:12). By this he sanctified his head (Num_6:11) to the Lord, so that the consecration of the Nazarite culminated in his uncut hair, and expressed in the most perfect way the meaning of his vow (Oehler). Letting the hair grow, therefore, was not a sign of separation, because it was the Israelitish custom to go about with the hair cut; nor a practical profession of a renunciation of the world, and separation from human society (Hengstenberg, pp. 190-1); nor a sign of abstinence from every appearance of self-gratification (Baur on Amo_2:11); nor even a kind of humiliation and self-denial (Lightfoot, Carpzov. appar. p. 154); still less a “sign of dependence upon some other present power” (M. Baumgarten), or “the symbol of a state of perfect liberty” (Vitringa, obss. ss. 1, c. 6, §9; cf. Num_6:22, Num_6:8). The free growth of the hair, unhindered by the hand of man, was rather “the symbol of strength and abundant vitality” (cf. 2Sa_14:25-26). It was not regarded by the Hebrews as a sign of sanctity, as Bähr supposes, but simply as an ornament, in which the whole strength and fulness of vitality were exhibited, and which the Nazarite wore in honour of the Lord, as a sign that he “belonged to the Lord, and dedicated himself to His service,” with all his vital powers.
(Note: In support of this explanation, Oehler calls to mind those heathen hair-offerings of the Athenian youths, for example (Plut. Thes. c. 5), which were founded upon the idea, that the hair in general was a symbol of vital power, and the hair of the beard a sign of virility; and also more especially the example of Samson, whose hair was not only the symbol, but the vehicle, of the power which fitted him to be the deliverer of his people.)


I just had an interesting thought too...why should we assume Paul was completely bald? Im sure he cut it short, but I don't see why it necessarily means bald ie noting but skin.
