פֶּ֫רַע

For the entire period of his vow of separation, no razor shall touch his head. He must be holy until the time of his separation to the LORD is complete; he must let the hair of his head grow long.

I will make My arrows drunk with blood, while My sword devours flesh—the blood of the slain and captives, the heads of the enemy leaders.”

They must not shave their heads or let their hair grow long, but must carefully trim their hair.
