II Sam 10: 4-5 When Davids men were captured by Hunun, their captors shaved off half of each mans beard. ( yes they ALL had beards)
To be without a beard was considerered a shame ( you know a like a women who had her shorn to humilate her, was a shame)
Rather than just shave off the half beard that was left and then go home, they were told to stay at Jericho, till their beards grew back out. They were ashamed to be without their beard.
We speak of gender distinction between the sexes.... BEARDS are the true bible distinction between the sexes NOT DRESSES AND PANTS.
In our American culture today, the beard is no longer considered a salutation, it's no longer a custom to swear by it.
The only thing sinful about facial hair or beards on men today is that some of us have made an isssue out of it.
Some have made it salvational or a test of fellowship. That is SINFUL to do that.
