Leviticus 21:10

And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes;

"'He who is the high priest among his brothers, upon whose head the anointing oil is poured, and that is consecrated to put on the garments, shall not let the hair of his head hang loose, nor tear his clothes;

And he that is the high priest among his brethren, upon whose head the anointing oil is poured, and that is consecrated to put on the garments, shall not let the hair of his head go loose, nor rend his clothes;

`And the high priest of his brethren, on whose head is poured the anointing oil, and hath consecrated his hand to put on the garments, his head doth not uncover, nor rend his garments,

The priest who is highest among his brothers, who has had the anointing oil poured on his head and has been ordained to wear the priestly garments, must not let his hair hang loose or tear his garments.
