Imamat 15:17

15:17 and he must wash in water any clothing or leather that has semen on it, and it will be unclean until evening.

Imamat 21:11

21:11 He must not go where there is any dead person; ¹  he must not defile himself even for his father and his mother.

[21:11]  ¹ tc Although the MT has “persons” (plural), the LXX and Syriac have the singular “person” corresponding to the singular adjectival participle “dead” (cf. also Num 6:6).
