Leviticus 19:27

Ye shall not round the corners your heads - This and the following verse evidently refer to customs which must have existed among the Egyptians when the Israelites sojourned in Egypt; and what they were it is now difficult, even with any probability, to conjecture. Herodotus observes that the Arabs shave or cut their hair round, in honor of Bacchus, who, they say, had his hair cut in this way, lib. iii., cap. 8. He says also that the Macians, a people of Libya, cut their hair round, so as to leave a tuft on the top of the head, lib. iv., cap. 175. In this manner the Chinese cut their hair to the present day. This might have been in honor of some idol, and therefore forbidden to the Israelites.

The hair was much used in divination among the ancients, and for purposes of religious superstition among the Greeks; and particularly about the time of the giving of this law, as this is supposed to have been the era of the Trojan war. We learn from Homer that it was customary for parents to dedicate the hair of their children to some god; which, when they came to manhood, they cut off and consecrated to the deity. Achilles, at the funeral of Patroclus, cut off his golden locks which his father had dedicated to the river god Sperchius, and threw them into the flood: -

Στας απανευθε πυρης ξονθην απεκειρατο χαιτην,π

Την ῥα Σπερχειῳ ποταμῳ τρεφε τηλεθοωσαν·π

Οχθησας δ ' αρα ειπεν, ιδων επι οινοπα ποντον·π

Σπερχει ' αλλως σοι γε πατηρ ηρησατο Πηλευς. κ. τπ . λπ .
