'Sin offerings' in the Bible

In the porch leading in front of the gate there were two tables on either side for slaughtering burnt offerings, sin offerings, and guilt offerings,

Then he told me, "The north and south chamber, which are opposite the courtyard, are consecrated areas where the priests who approach the LORD will eat consecrated offerings and lay the consecrated grain offerings, sin offerings, and guilt offerings, because the area is holy.

On the fifteenth day of the seventh month, during a seven day festival, the Regent Prince is to present these as daily sin offerings, burnt offerings, and grain offerings mixed with oil.'"

about which he said, "This is where the priests will be boiling the guilt and sin offerings and baking the grain offerings so they don't bring them through the outer courtyard, thus diminishing the people's holiness."
