Insight from the Scriptures Vol 1, pg 1020
Hebrews.
The practice among Hebrew men from the first was to let the beard grow, but it was kept well groomed; and they trimmed the hair to a moderate length. In Absalom?s case, his hair grew so abundantly that when he cut it once a year, it weighed 200 shekels (2.3 kg; 5 lb), possibly made heavier by the use of oil or ointments. (2Sa 14:25, 26)
God?s law commanded Israelite men that they should not ?cut their sidelocks short around,? nor destroy the "extremity" of their beards. This was not an injunction against trimming the hair or beard but was evidently to prevent imitation of pagan practices. (Le 19:27; Jer 9:25, 26; 25:23; 49:32) To neglect the hair or beard, likely leaving them untrimmed and untended, was a sign of mourning. (2Sa 19:24) In instructions to priests given through the prophet Ezekiel, God commanded that they clip, but not shave, the hair of their heads and that they not wear their hair loose when serving in the temple.?Eze 44:15, 20.
Interesting that no reference is given to the first statement. The photo below is from Draw Close to Jehovah, pg 210.
