Leviticus 21:10-15 - Rules For The High Priest

¹⁰ "The high priest among his relatives whose head has been anointed with oil and who has been consecrated to put on the priestly clothing is not to let his hair hang loose or to tear his clothes. ¹¹ He is not to come near any dead body whether the deceased is his father or his mother so as not to defile himself. ¹² He is not to go out of the sanctuary or defile the sanctuary of his God, because his God's consecrating oil of anointing rests on him. I am the LORD.

¹³ "Furthermore, he is to marry a true virgin. ¹⁴ He is not to marry a widow or one who has been divorced, has been defiled, or has been a prostitute. Instead, he is to take a virgin from among his people as his wife. ¹⁵ "He is not to defile his children among his people, because I am the LORD, who sets him apart."
