The mode of wearing it was definitely prescribed to the Jews (Lev. 19:27; 21:5). Hence the import of Ezekiel's (5:1-4) description of the "razor" i.e., the agents of an angry providence being used against the guilty nation of the Jews. It was a part of a Jew's daily toilet to anoint his beard with oil and perfume (Ps. 133:2). Beards were trimmed with the most fastidious care (2 Sam. 19:24), and their neglet was an indication of deep sorrow (Isa. 15:2; Jer. 41:5). The custom was to shave or pluck off the hair as a sign of mourning (Isa. 50:6; Jer. 48:37; Ezra 9:3). The beards of David's ambassadors were cut off by hanun (2 Sam. 10:4) as a mark of indignity. On the other hand, the Egyptians carefully shaved the hair off their faces, and they compelled their slaves to do so also (Gen. 41:14). Western Asiatics have always cherished the beard as the badge of the dignity of manhood, and attached to it the importance of a feature. The Egyptians, on the contrary for the most part shaved the hair of the face and head, though we find some instances to the contrary. The beard is the object of an oath, and that on which blessing or shame is spoken of as resting. The custom was and is to shave or pluck it and the hair out in mourning, (Ezra 9:3; Isaiah 15:2; 50:6; Jeremiah 41:5; 48:37) Bar. 6:31; to neglect it in seasons of permanent affliction, (2 Samuel 19:24) and to regard any insult to it as the last outrage which enmity can inflict. (2 Samuel 10:4) The beard was the object of salutation. (2 Samuel 20:9) The dressing, trimming, anointing, etc., of the beard was performed with much ceremony by persons of wealth and rank (Psalms 133:2) The removal of the beard was a part of the ceremonial treatment proper to a leper. (Leviticus 14:9)
