להקריב השוגג במעילה, או החוטא בגזילה, או בשפחה חרופה, או שכפר בפיקדון ונשבע; מביא קרבן אשם, וזה הוא הנקרא אשם ודאי.
For [the following individuals:] a person who unknowingly used sacred property, a person who sinned by stealing, one [who had relations with] a maidservant designated for another person, or one who denied possession of an entrusted object and took a [false] oath, to bring a guilt offering. This is referred to as "the unconditional guilt offering."
