Bible Verses About Trespass Offering: For involuntarily touching unclean things

If a person touches something unclean, whether the carcass of an unclean wild animal, a domestic animal or a reptile, he is guilty, even though he may not be aware that he is unclean.

If he touches some human uncleanness, no matter what the source of his uncleanness is, and is unaware of it, then, when he learns of it, he is guilty.
