From Manners and Customs of the Bible:

Leviticus 7:1. This is the law of the trespass offering.
The trespass offering was similar to the sin offering; yet there were several important points of distinction. In the trespass offering rams were offered, and the blood was sprinkled around the altar of burnt offering (Lev. 5:18; Lev. 7:2). The priest was required to make a special valuation of the ram offered (Lev. 5:15-16).
The trespass offering was offered in cases of trespass committed in holy things: dishonesty or falsehood in a trust; robbery joined with deceit; dishonesty and falsehood in reference to things found (Lev. 5:15-6:7).
