'Shave' in the Bible

“Now you, son of man, take a sharp sword, use it as you would a barber’s razor, and shave your head and beard. Then take a set of scales and divide the hair.

They shave their heads because of youand wrap themselves in sackcloth.They weep over youwith deep anguish and bitter mourning.

Neither shall they shave their heads, nor suffer their locks to grow long; they shall only poll their heads.
