About those offerings…

We now turn attention to the sacrifices that are responses to offense: the so-called sin offerings and guilt offerings. These sacrifices feature blood rituals prominently (whereas blood is rarely used outside of them), with the logic being that life is in the blood (Lev 17:11). Blood rituals are uncommon in the rest of the ancient world. Animals are offered to other deities, but blood manipulation is not generally involved. In Israelite practice, the Torah establishes these two sacrifices as responses when some impurity encroaches on the sanctuary (sin offering) or when something that belongs to the sanctuary is appropriated for personal use (guilt offering).—Walton and Walton, The Lost World of the Torah, 75
