'Mustache' in the Bible

The person with the infectious skin disease is to tear his garments and loosen his hair. He is to cover his mustache and shout out, "Unclean! Unclean!'

Meanwhile, Saul's grandson Mephibosheth also went out to greet the king. He had not taken care of his feet, trimmed his mustache, or washed his clothes from the day the king left until the day he returned safely.

Groan quietly; do not observe mourning rites for the dead. Put on your turban and strap your sandals on your feet; do not cover your mustache or eat the bread of mourners.”

Then you will do just as I have done: You will not cover your mustache or eat the bread of mourners.
