'Mustache' in the Bible

“As for the leper who has the infection, his clothes shall be torn, and the hair of his head shall be uncovered, and he shall cover his mustache and cry, ‘Unclean! Unclean!’

Then Mephibosheth the son of Saul came down to meet the king; and he had neither cared for his feet, nor trimmed his mustache, nor washed his clothes, from the day the king departed until the day he came home in peace.

Groan silently; make no mourning for the dead. Bind on your turban and put your shoes on your feet, and do not cover your mustache and do not eat the bread of men.”

You will do as I have done; you will not cover your mustache and you will not eat the bread of men.
