Leviticus 21:10-12

Amplified Bible, Classic Edition

¹⁰ But he who is the high priest among his brethren, upon whose head the anointing oil was poured and who is consecrated to put on the [sacred] garments, shall not let the hair of his head hang loose or rend his clothes [in mourning],

¹¹ Neither shall he go in where any dead body lies nor defile himself [by doing so, even] for his father or for his mother;

¹² Neither shall he go out of the sanctuary nor desecrate or make ceremonially unclean the sanctuary of his God, for the crown or consecration of the anointing oil of his God is upon him. I am the Lord.
