Final answer:
In Leviticus 11:28, a person who has touched a dead carcass must wash their clothes and stay outside the camp until evening; no offerings are required.
Step-by-step explanation:
According to Leviticus 11:28, a person who picks up a dead carcass is considered unclean, and to become clean, they must wash their clothes and stay outside the camp until evening. No offerings, whether purification offerings or grain offerings, are required for touching dead carcasses according to this specific instruction. The process of purification outlined in various religious texts often involves rituals which symbolize a return to cleanliness both physically and spiritually after having come into contact with causes of ritual impurity, such as dead bodies.
