 Hair
    (1.) The Egyptians let the hair of their head and beard grow
    only when they were in mourning, shaving it off at other times.
    "So particular were they on this point that to have neglected it
    was a subject of reproach and ridicule; and whenever they
    intended to convey the idea of a man of low condition, or a
    slovenly person, the artists represented him with a beard."
    Joseph shaved himself before going in to Pharoah (Gen. 41:14).
    The women of Egypt wore their hair long and plaited. Wigs were
    worn by priests and laymen to cover the shaven skull, and false
    beards were common. The great masses of hair seen in the
    portraits and statues of kings and priests are thus altogether
    artificial.
      (2.) A precisely opposite practice, as regards men, prevailed
    among the Assyrians. In Assyrian sculptures the hair always
    appears long, and combed closely down upon the head. The beard
    also was allowed to grow to its full length.
      (3.) Among the Greeks the custom in this respect varied at
    different times, as it did also among the Romans. In the time of
    the apostle, among the Greeks the men wore short hair, while
    that of the women was long (1 Cor. 11:14, 15). Paul reproves the
    Corinthians for falling in with a style of manners which so far
    confounded the distinction of the sexes and was hurtful to good
    morals. (See, however, 1 Tim. 2:9, and 1 Pet. 3:3, as regards
    women.)
      (4.) Among the Hebrews the natural distinction between the
    sexes was preserved by the women wearing long hair (Luke 7:38;
    John 11:2; 1 Cor. 11:6), while the men preserved theirs as a
    rule at a moderate length by frequent clipping.
      Baldness disqualified any one for the priest's office (Lev.
    21).
      Elijah is called a "hairy man" (2 Kings 1:8) from his flowing
    locks, or more probably from the shaggy cloak of hair which he
    wore. His raiment was of camel's hair.
      Long hair is especially noticed in the description of
    Absalom's person (2 Sam. 14:26); but the wearing of long hair
    was unusual, and was only practised as an act of religious
    observance by Nazarites (Num. 6:5; Judg. 13:5) and others in
    token of special mercies (Acts 18:18).
      In times of affliction the hair was cut off (Isa. 3:17, 24;
    15:2; 22:12; Jer. 7:29; Amos 8:10). Tearing the hair and letting
    it go dishevelled were also tokens of grief (Ezra 9:3). "Cutting
    off the hair" is a figure of the entire destruction of a people
    (Isa. 7:20). The Hebrews anointed the hair profusely with
    fragrant ointments (Ruth 3:3; 2 Sam. 14:2; Ps. 23:5; 45:7,
    etc.), especially in seasons of rejoicing (Matt. 6:17; Luke
    7:46).
