Leviticus 22:5

New Century Version

from touching any unclean crawling animal, or from touching an unclean person (no matter what made the person unclean).

See the chapter Copy

But all other insects that have wings and walk on four feet you are to hate.

“ ‘When a woman has her monthly period, she is unclean for seven days; anyone who touches her will be unclean until evening.

Anyone who touches the person who discharges the body fluid must wash his clothes and bathe in water; he will be unclean until evening.

Anyone who touches those things will become unclean until evening. That person must not eat the holy offerings unless he washes with water.

Anything an unclean person touches becomes unclean, and whoever touches it will be unclean until evening.”
