Leviticus 5:6

His trespass-offering But how come confession and sacrifice to be necessary for him that touched an unclean thing, when such persons were cleansed with simple washing, as appears from Leviticus 11., and Numbers 19.? This place speaks of him that being so unclean did come into the tabernacle, as may be gathered by comparing this place with Numbers 19:13; which if any man did, knowing himself to be unclean, which was the case there, he was to be cut off for it; and if he did it ignorantly, which was the case here, he was, upon discovery of it, to offer this sacrifice.
