English: “And if a soul” — an individual is liable for a chatas offering only for a matter whose intentional violation is kares and whose inadvertent is chatas.
Kares/chatas threshold for the individual — ordinary individuals, like the nasi and community, bring chatas only for kares-level prohibitions.
An ordinary person is obligated in a chatas only when the prohibition in question carries kares if done intentionally. Lesser prohibitions that lack this severity do not generate the private chatas of this chapter, just as they do not generate the communal or nasi offerings.
