Everything here runs on one word. These sin offerings apply only to sin committed bishgagah, by mistake; Numbers 15:30 states the exclusion outright. The grading runs opposite to Hammurabi — there the penalty falls with the victim’s rank, here the price rises with the offender’s, and the priest pays a bull. There is also a live argument about whether the offering cleans the sinner at all: the blood never touches the person.
